Summary and detailed reports



Lesson 1 - The Workspace

LEGENDplex™ is similar to Microsoft Office products, which places a greater emphasis

on visual orientation to software features to facilitate ease of use. The hierarchy is that

Ribbons contain Tabs, Tabs contain Groups, and Groups contain Tasks.

Click to hide/display the tabs details.

Figure 1. LEGENDplex™ Ribbon

Ribbons

Ribbons contain both tabs and groups, along with access buttons for different functions.

Tabs

Tabs are a set of groups, organized by similar function.

For example, the Analysis tab contains the Wizard, Preference, Edit, Analysis,

Protocol and Gating groups. These groups are all related because they are the commonly

used groups of tasks during the analysis process.



Groups

Groups are a set of similar features or program tasks similar to menus, but with images,

and tool tips.

For instance, the View group contains 3D, Bar Chart, Standard Curve and Sample

Detail. These are all visual presentations of results but in different forms.

Lesson 2 – Quantitative Wizard

1. Click to start a new quick wizard session.

2. Click to open the Add Files dialog box.



3. Select the files to be analyzed and drag them to the FCS Files list. You can also drag

the file folder to the FCS Files list; LEGENDplexTM

will load all the .fcs or .lmd files

in this file folder.



4. Click Next and adjust the parameters on the Settings panel according to the assay. In

the example shown above, we set Highest Conc. to 4000, Dilution Factor to 4, and

Decimal Places to 0.

The AABBCC mode will replicate samples in consecutive manner when the number

of replicates is defined (e.g. sample 1, sample 1; sample 2, sample 2; …..). The

ABCABC mode will replicate samples in repeating groups with defined group size

(e.g. sample 1, 2, 3, 4…; sample 1, 2, 3, 4…).

It is recommended that the Auto Gate be set at OFF position.

Although a single highest standard concentration is set here, you will have options in

Wizard Step 8 to assign different concentrations to different analytes if they are

different.



5. Click Next. Sort the loaded files to the order you need by clicking the column titles

File Name, or Data modified in the file list, the program will sort the files in

ascending/descending order.

In your experiment, if you follow the LEGENDplex™ kit Plate Map or Rack Map and

acquire data for standards and samples in the same sequential order as that in the

Plate Map, you can do file sorting by clicking on Date modified to put files in correct

order, select the consecutive files and then click on to apply the

standard curve parameters according to the default Settings.

Note: You should click to apply the curve options whenever a

parameter of Standard Curve settings has been altered.

If the FCS files for the standard curve are inconsecutive in the list, you can press and

hold down the Ctrl key and select the files in the correct order of the standard curve,

then right click Apply Curve Options.

Alternatively, you may drag the small round buttons labeled as C0, C1, C2…on the

top of the file list individually to appropriate files corresponding to the standard

points (such as C0 for the 0 Standard, C1 to the lowest standard concentration, C2 for

the second lowest concentration of the standard curve, etc.). To define sample



replications and dilution factors, you may highlight selected samples, then right click

your mouse and go to Edit Samples functions.

6. Click Next, the Bead Gating window will pop up automatically. Adjust # of Bead

Size, Report Signal, # of Beads for Size 1, and # of Beads for Size 2 and select the

axis for the dot plots. Click the arrow to unfold the detail of Bead Size and define the

Bead ID and Analyte, if so desired. When entering Bead ID information, always

enter the Bead IDs in increasing alphabetical order (e.g. A4, A5, A6…, the B2, B3,



B4…).

You will need to select the X-axis and Y-axis labels (channels) of the bead dot plots.

The channels vary depending of the flow cytometer used to collect the data. The

default settings are for the BD FACSCaliburTM

instrument.

Then click on the top of the Bead Gating window, LEGENDplex™

will find bead areas automatically.

For LEGENDplex™ beads-based assays, the auto gating works well if you follow the

kit protocols and the flow cytometer used for sample reading is properly set up and

compensated (if needed). If for some reason autogating failed to properly separate the

bead populations, please use following options:

a. Decrease Gate Setting (e.g. from 100 to 50), or

b. Use manual gating: You may need to click on and then click on the bead

population to remove the gate set by auto gating. Click and then draw a gate

around the bead size population(s). The new gating will automatically apply. If

you find that the Band Panel (lower panel) is not acceptable, you may also use

Type here Bead ID and analyte

identity, as provided in the

instruction manual of the kit.



to erase the rectangular gate for a particular population and re-draw a new

gate using .

After manual gating if you click on , it will remove all manual

gating.

c. Use a different sample to do gating. This is usually the most practical method.

You can click to save current gate settings to a gating protocol.

7. Click to finish gating. Once completed, click .



Standard curves and data calculation options can be edited using the two buttons

labeled as Curve and Options.

Variations in standard concentrations for different analytes can be modified in the

Curve and Options. Curve fitting method can also be changed in Options.

If you forget to define files for standard curves in Step 5, the Curve and Option

button may not work. You will need to click on the Previous button to go back to the

previous page to define the files used for standard curves.

8. Click . A Process window will pop up to show you the analysis process.



The result will be displayed as shown below.

9. Click View on the Ribbon menu and select a view type to see different results. You

may use this function to view selected sample concentrations in a 3D or 2D graph

format. The image can be saved or copied by right clicking your mouse.



10. Click Report on the Ribbon menu and select a report type to generate a report. The

report can be printed directly or exported to Excel, Word or PDF files.

Lesson 3 – Qualitative Wizard

1. Click to start a new quick wizard session.

2. Click to open the Add FCS Files dialog box.



3. Select the .fcs files or .lmd files (a special form of .fcs files) and drag them to the

FCS Files list. You can also drag the file folder to the FCS Files list;

LEGENDplexTM

will load all the .fcs files in this file folder. Once the .fcs files are

loaded, the workspace will be displayed as below:



4. Click Next; select Qualitative as Type in Settings.



5. Click on the bottom left of the window to do gating procedure.

6. Click Next to go to the next step.

7. Do the followings if necessary.

Edit Sample ID

Edit Options



8. Click . A Process window will pop up to tell you the analysis process.



9. The result will be displayed as below.

Next time, you can load the shared files from a network drive when loading FCS files.



Set Standard Curve Manually

If the FCS files for the standard curve are in the middle of the file list, you may drag the

small round buttons labeled as C0, C1, C2….. on top of the file list individually to

appropriate files corresponding to the standard points (such as C0 for the 0 Standard, C1

for the lowest standard concentration, and C2 for the second lowest concentration of the

standard curve, etc.).

You can also select C from the drop down list of Type column in the FCS Files list and

manually type a concentration in the Concentration column.

The designates a sample and to ( please change to C0 to C7) indicates

calibrators (i.e. Standards). Move the mouse over the icons, a tooltip will display the

theoretical standard concentration according to Quantitative Settings.

Alternatively, the files corresponding to Standards can be highlighted and right clicked to

change file types to C. The standard concentrations can be typed in the Concentration

column.

Data Sorting

In the FCS Files list, the column title such as File Name, and Data modified can be used

to sort the files in ascending/descending order. Common use of the sorting function is to

arrange the order of files for standard curves to match with experimental layout so that

data can be calculated correctly.

Replicates

Sample replicates can be defined in two ways:

1. Double click the Name column of the FCS files for the samples in the FCS Files

list and type in the same name for sample replicates, or



2. Highlight samples, right click in the FCS Files list and select Edit Name to open

the Define Names dialog box. Define the Replicate Mode and Replicate

Number.

it is the replicate of the well above.

Step3:

Enter a value for the highest concentration, dilution factor for the standard

curve and the number of decimal digits for the calibrated sample concentrations.

Check Background (C0) check box to indicate that the standard curve files

include background wells. Uncheck it to indicate the standard curve files do not

include background files.

Check Direction: Increasing to define standards curve files that have a serial

dilutions from low to high (upward curve shape); or uncheck Direction

Increasing for standard concentrations from high to low (downward curve



shape). Increasing is used most often with typical sandwich assays involving S

shaped curves. Decreasing is often used for competition assay curves.

If all analytes have same starting concentrations, select Apply to All Analytes

check box (default). Click button to continue.

If not all analytes have the same starting concentrations, uncheck the box for

Apply to All Analytes, select the analytes which share the same concentrations,

enter the concentration in the Highest Concentration box, and then click

for these selected analytes. Repeat the same operations for other

targets which have different highest concentrations. When all analytes are

defined, click OK button.

Lesson 5 - Gating

Gating is the process of separating bead populations. Bead size populations can be further

gated to generate subpopulations. LEGENDplex™ Data Analysis Software offers

automatic tools and advanced manual gating tools to facilitate this process.

First, open the Bead Gating window. Select any sample and click on the left bottom

or the same icon on the Analysis ribbon tab at Wizard step 6.

Gating Toolbar provides a series of tool to finish the gating process.

Gate Setting is where to define the gating parameters.

The Size Panel and Band Panel display the gating results.

In Qualitative wizard, the only difference is the part in Gate Settings as shown below:



Gating Protocol

Gating protocol is a .gating.xml file which contains gate setting and gating results. You

can load a saved gating protocol file by clicking to browse.

Also you can click to save current gating setting and apply gating results to a

gating protocol.

Auto Gating

Adjust the value of # of Bead Size, #Bead of Size 1, Size 2 and change the x and y axis

parameters of the Size Panel and the Band Panel to match the experiment.

To define the size, choose SSC-H in the y axis and FSC-H in the x axis of the Size

(upper) panel. To define the subpopulations of beads, choose FL3 or FL4 in the y axis

and FL2 in the x axis of the Band (lower) panel. The selection may vary with data

acquisition software on flow cytometers and user should select appropriate parameters for

proper display of data.



Then click on the top of the Bead Gating window, LEGENDplex™ will find

bead clusters automatically.

Manual Gating Tools

If there is severe background noise which may affect the gating process or the gating

results don’t match your expectation, LEGENDplex™ provides a set of tools to perform

gating manually.

Add a polygon cluster in Size Panel or a rectangle in Band Panel.

Delete a cluster in Size Panel or Band Panel.
