I don't have the recipe easily at hand but the reference is Analytical 
Biochemistry, V150, p76-85 Smith et al: Measurement of protein using 
bicinchoninic acid.
I use 200ul BCA soln + 20ul sample in a 96 well plate. 37oC 30min then 
read in an ELISA plate reader at 562nm.
Great Assay. Easy and painless
