โฆ Synopsis
An alkaline-copper reagent is described which forms a soluble, stable complex with protein in the presence of detergent. The modified reagent produces a relatively uniform absorbance for six different proteins, and it may be used to determine the protein content of such heterogeneous samples as plasma membranes and mitochondria.

A rapid method for the estimation of inorganic phosphate in the presence of high concentrations of protein is described. In this procedure protein precipitation is prevented by inclusion either of guanidine hydrochloride or of urea. The assay is based on the observation that the solubilized phosphom
