詳細

細胞株の説明

This is a derviative of the CHO-K1 cell line, ECACC catalogue no. 85051005 which has been adapted to grow in the animal component free medium, CHO PF Media (C5467)

培地

CHO PF Media (C5467) + 8mM L-Glutamine (G7513). When freezing cells use freeze medium composed of 50:50 fresh:conditioned medium + 10% DMSO.

継代と培養方法

Maintain cultures between approximately 3-9 x 10⁵ cells/ml; 5% CO₂; 37°C. Cells grow as aggregates in suspension. Viability may be poor on resuscitation and may initially decrease further. Full recovery may take up to 2 weeks. A centrifugation step to remove the cryoprotectant is essential. Rapidly thaw the frozen ampoule in a water bath at 37°C for 1-2 minutes. Transfer the contents to a centrifuge tube and slowly add 5-10ml of pre-warmed growth media. Remove a sample for counting. Centrifuge at 100g for 2-3 minutes to pellet cells and seed at a relatively high density of 5-7 x 10⁵ cells/ml. Leave culture flask upright and observe regularly until viable proliferating cells are seen. Once established use a split ratio of 1:2 approximately every 4 to 5 days.
