Casein.--Casein was obtained by purifying a quantity of imported casein according to the method of Hammarsten as modified by Robertson. 1 This was designated by the symbol R. A casein, the history of which was completely known, so as to overcome the ques-

properties of preparations of acid casein (Hammarsten_, I883) were surprisingly constant led to the assumption that casein was a single protein. The work of Osborne and Wakeman (1918) and later that of Linderstrom-Lang and Kodama (l925)j employing extraction and precipitation methods, found that it …

These blocking buffers contains casein protein that is purified from milk by the Hammarsten method. This, however, can be obviated or controlled by adding a few drops of octyl alcohol, or by using a stirrer free from vibration, or by having the vessel that contains the.milk about double the capacity required to hold the amount of milk used, which will usually provide sufficient room to accommodate the foam; any foam forming subsides promptly when the coagulation of the casein takes place. 132 Preparation of Pure Casein After standing under gentle stirring for 3 hours with acidity just The chemically reactive lysine content of untreated casein was 99.6%, and of heated casein was 67.1%. Heat treatment of casein resulted in significantly decreased lysine bioavailability as estimated by all methods.
