Oxygen consumption

Postby Mila » Fri Oct 11, 2013 12:19 pm

Hello everyone.

I was reading some information about oxygenation effects on cell cultures and I found the following:

"Mammalian cells consume oxygen at rate of 0.05-0.5micromol/10^6 cells/hour. Cell cultures for tissue engineering have relatively large cell densities (10^6 cells/mL) which results in total oxygen depletion in 0.4-4 hours."

Could anyone explain to me how they calculated the time required for cells to consume all the oxygen?

I forgot to add that air-saturated aqueous media contains 21mM oxygen

You answered it by yourself. You have number of cells, how much oxygen they need and how much oxygen there is. That should be an easy math.

Cis or trans? That's what matters.
