Destaining a coomassie sttained gel - (May/13/2010 )

Type of concentration (ie. v/v, w/v or w/w) is not stated in the article and I assumed (for simplicity) that it is v/v.

I need 12.5% which is 125 mL of "pure acid" per 1000 mL

85% acid is 80 mL of "pure acid" per 100 mL

125 - x
80 - 100
---
(125*100)/80 = approx. 147

yeah i assumed that this is what you would have done!!!

(typo - there should be 85 not 80 in ratio calculation)
