What are you using to calibrate your protein concentrations? Why not use
Horseradish peroxidase, that you have bought from Sigma! I guess that might
defeat the object. By extinction - do you mean absorbance? Or extinction
coefficient? There is A=e c l, where A is absorbance of sample, e is the
molar extinction coefficient, c is concentration and l is pathlength...
Beer Lambert I think it is called...
