Abstract
Prof. Kurt H. Meyer and his co-workers1,2 have recently succeeded in the crystallization of α-amylase from pig's pancreas. The molecular weight of the substance, kindly supplied by Prof. Meyer, has been determined from sedimentation and diffusion experiments. The dried substance was dissolved in a buffer solution of pH 8.4, with a molarity of 0.2 in sodium chloride, 0.02 in boric acid and 0.005 in borate.
