The phosphate- and Tris-buffered saline formulations are used for blocking excess binding sites on membranes and microplates in antibody-based detection methods. The term casein, as will be used in this report, refers to that mixture of proteins which is obtained by the method of acid precipitation. Casein prepared by other methods will be so designated, where necessary. The method of Hammarsten is the best known of the earlier methods for the laboratory preparation of casein (2).

These blocking buffers contains casein protein that is purified from milk by the Hammarsten method. Hammarsten (3), in 1877 , greatly improved the method of prepara- tion of casein, which with few modifications is still used by modern investigators. He (3) also discovered that casein decomposes CaCO3 liberating COs, which indicated that this protein is an acid.
