Dear Members,How well is extinction coefficient based protein concentration 
measurement accuracy established. It seems that several monograph based protein 
HPLC assays use 214 for the same. How accurate are extinction coefficients for 
the same proteins. Is there any consensus if which one is more accurate for 
estimation. Some glycoprotein  monographs use extinction coefficients.
