Bacteria....

I dont think there is a solution... sorry ! Discard your contaminated cells as soon as possible....

Agree with Neurite, throw your cells out and start again.

The only solution is to use good aseptic technique to avoid contaminating your cells again.

Hi,

Are you not using any asntibiotic like penicilin and sreptomicin??

If not, use these. And throw these culture and revive new culture

Good Luck

You should be able to do tissue culture with no antibiotics in your media.
