HiKaryoXLTM Nutrient Mixture F-10 MediumWith L-Glutamine, FBS, Penicillin, Streptomycin and Sodium bicarbonate
Without Phytohemagglutinin (PHA-M)
1X liquid Karyotyping Medium
Product Code: AL185A
Product description:
HiKaryoXL Nutrient mixture F-10 Medium is a medium
developed for the short term in vitro culture of peripheral
blood lymphocytes for cytogenetic studies. Cytogenetic
studies include metaphase and pro metaphase studies carried
out on lymphocytes to detect chromosomal aberrations
associated with structural and numerical abnormalities.
Lymphocytes come from normal peripheral blood and are
mitotically inactive, hence have to be stimulated with a
mitogen. The most common mitogen used for the stimulation
of cell division in lymphocyte cultures is Phytohemagglutinin
(PHA-M). Phytohemagglutinin is a lectin extract from red
kidney bean (Phaseolus vulgaris). The protein consists of twosubunits, a leucoagglutinin (PHA-L) and an erythroagglutinin
(PHA-E). PHA-M is the mucoprotein form and is used for
stimulation of cell proliferation in lymphocyte culture.
HiKaryoXL Nutrient Mixture F-10 Medium is a
karyotyping medium composed of a basal medium Nutrient
Mixture F-10 and supplemented with L-Glutamine, FBS,
Penicillin, Streptomycin and Sodium bicarbonate. It does not
contain PHA-M, hence if required, has to be added prior too
use.

Directions:
1. Add PHA-M to HiKaryoXLTM Medium in required
concentration (5-15g/ml) prior to inoculation of blood.
2. Add whole blood to 10ml of this medium containing
PHA-M in T-25cm2 flasks as per the following
recommendations:
Normal adults - 0.8ml
Infants and children- 0.6ml
Women (during pregnancy/ postpartum) - 1.0ml
Note: If required,.3. Incubate the flasks at 37OC and 5% CO2for 67-72 hours.
4. To determine optimum incubation time i.e. the peak
mitotic index, collect samples at different time intervals
between 48-72 hours.
Note: Peak mitotic index is most commonly observed at
67-72 hrs.
5. Add 100l of 10g/ml of colchicine and incubate for
additional 2 hours.
Note: Incubation time of less than 1 hour might result in
reduced mitotic index
6. Transfer the entire content of the flask to a sterile
centrifuge tube and centrifuge at 800-1000rpm for 10
minutes.
7. Discard the supernatant and resuspend the pellet in 5ml of
hypotonic 0.075M KCl solution and incubate in a water
bath at 37oC for 15-20 minutes.
Note: Add KCl solution drop wise while agitating the
cells
8. Add equal amount of freshly prepared ice cold fixative
(Acetic acid : methanol, 1:3 parts)
9. Centrifuge cells at 800-1000rpm for 10min.
10. Discard the supernatant and again add 5ml of freshly
prepared ice-cold fixative (acetic acid: methanol, 1:3
parts) with constant mixing. Leave the cells at 4oC for
10-15 min.
11. Centrifuge the cells at 1000rpm for 10 minutes.
12. Repeat step no. 10 and 11.
13. Discard the supernatant and resuspend the pellet in 0.2ml
of fresh fixative.
14. Put 1 drop of cell suspension on to a clean, cold slide.
Tilt the slide and let the drop run down the slide as it
spreads and dry the slide rapidly over a hot plate or a
beaker of boiling water.
15. Stain the slides as required.

Quality control:AppearanceOrangish colored, clear solution
pH7.00 -7.60
Osmolality in mOsm/Kg H2O320.00 -360.00
SterilityNo bacterial or fungal growth is observed after 14 days ofincubation, as per USP specification.
Cultural ResponseThe growth promotion capacity of the medium is assessed
qualitatively by analyzing the cells for the morphology andquantitatively by estimating mitotic index.
Storage and shelf life:
Store at -20C. The medium can be aseptically transferred
into smaller aliquots for convenience. Once thawed, use themedium within 30 days.
Avoid exposure to light.Shelf life is 12 months.
Use before expiry date given on the product label.
Following troubleshooting tips can be used in
case of no growth or slow growth:
Cause Solution
Toxic collection
equipment
Check collection equipment. Do a
controlled experiment to rule out
toxicity.
Specimen received in
lithium heparin, EDTA,phenol-preserved heparin,
or other wrong
preservative
Request another specimen if
possible. Wash blood severaltimes before setting up to
increase chances of growth.
Improper shipment or
storage of sample
Check shipment variables: time
passed between collection and
receipt, temperature control,
pressure control, proper pH of
transport medium.
Faulty glassware or plastic
ware
Try another lot or brand of
pipette, flask, Petri dish,
coverglass etc.
PHA- unresponsive culture Try pokeweed mitogen,
Concanavalin A, another
mitogen, or two mitogens. Repeat
the test at a later date if possible.
