Ship in dry ice;

Store in liquid nitrogen.


Cell Count: 3-5x 106 Cells/tube x 3 tubes

Inactivated: by irradiation

Sterility: no microbial growth detected

Mycoplasma: no mycoplasma growth detected

Antibiotics Resistance: Puramycin resistant

Plating Efficiency: > 70% cells adhere within 24 hours of plating

Monolayer Formation: forms confluent monolayer within 2days of plating

ES Cell Maintenance: supports growth of non-differentiated human and mouse ES cells

Plating and Storage Instruction:

Store the cells in Liquid nitrogen upon receiving. Thawing the cells at 37 oC water bath (do not over incubate), immediately transfer to mEF medium, then spin to pellet the cells using a bench-top centrifuge, such as Beckman-Coulter?s ALLEGRA 6R at 800 rpm. Re-suspend the cells with VERY GENTLE pipetting in an appropriate amount (10-20 mL) of a fresh DMEM medium containing 10% FCS, 1 x Antibiotics and 50 ?M ?-Mercaptoethanol and plate the cells on 0.1% gelatin treated plate.


? As feeder layer for mouse ES (mES) cells;

? As feeder layer for human ES (hES) cells.
