Sub-culture of N2a cells - (Oct/07/2009 )
Hi all. I'm trying to grow N2a cells at the moment. I got them from ATCC and followed the instructions enclosed. However, when I attempted to sub-culture my cells I ran into problems. After centrifugation my cells were really damaged and it has taken 3 weeks to get them to a very low 30-40% confluency. I had to change from minimal media using EMEM to DMEM to the DMEM/50% Opti-mem mix I am currently using.
Can anyone tell me how to what the optimim centrifugation speed is? The reason I use this step is to try and recover the non-adherent cells and remove debris.
I really need 80-90% confluent flasks and this is beginning to depress me. Any help appreciated!
You shouldn't be using over 100 RCF for centrifuging
