bicarbonate in cell culture: powder v. liquid?
Posted 13 December 2009 - 12:37 PM
The basic question is: can I add the bicarbonate just as a powder to the liquid medium? Or do I need to dissolve it in something first and then add?
Sorry for the silly question, I'm new to cell culture.

but, addition of powder may affect the pH of your medium.
you can prepare and adjust a solution of bicarbonate prior to addition to your medium or you can add powder and check and adjust the pH, as necessary (you may not be adding enough to have a significant effect).

Adding it can contaminate your medium.
I'd dissolve it first, sterilize it and then add it to the medium.
