transformation of competent cells - (Jul/09/2007 )

Hi to all ofyou hanging there

I have question may be silly one could any body tell me for how many days i can still use the transformed competent cells i mean if u transform 50 ul of ccs with 2 ul of ligation mixture then u add 950 SOC medium etc....then u plate 50 to 100ul can i keep the rest in 4C (900ul if i plate 100ul) please if somebody have tried it reply me

Once I did leave this mixture at RT O/N and plated them the next day. I normally don't store them and usually spread the entire volume on to the plates.

No idea abt storing them in 4C.

I reccommed not storing more than O.N. There is a drastic decrease in transformation efficiency if you use >O.N strored transformed cells.
Hope this helps
