RECOMMENDED QC PROTOCOL

M1 Bioassay

1. The M1 bioassay is performed using in vitro semi-solid agar cultures, which contain approximately 100 cells in 1 mL volumes of DME containing 20 % FCS in 0.3% agar.

2. Add 100 μL of sample or mLIF (10(E4) units/mL in 5% FCS in isotonic saline) in two-fold serial dilutions in duplicate to 35 mm petri dishes.

3. Add 100 μL of 5% FCS in isotonic saline to two control slides.

4. Incubate at 37°C in fully humidified atmosphere of 10% CO2 in air for 7 days.

5. Score the number of colonies that show differentiation (note: 50 units is defined as the amount of activity which results in 50% of the colonies being differentiated).
