The purpose of the present investigation was to develop a quick and simple method for the determination of beryllium in bcryl, gcncrally associated with the minerals of pcgmatitc origin. Beryllium is usually dctcrmined tither by gravimetric or photometric methods. In the gravimctric methods it is c
A protein assay is described in which the sample is precipitated with trichloroacetic acid in the presence of sodium dodecylsulfate, filtered off on a Millipore membrane and stained with Amidoschwarz 10B. The proteindye complex is eluted, and its absorbance determined at 630 nm. This assay is very r
