title: Some monotreme milk "whey" and blood proteins.
abstract: 1. Electrophoretic studies are made of mature phase milk "whey" proteins and blood serum proteins of echidna (Tachyglossus aculeatus) and platypus (Ornithorhynchus anatinus). The echidna milk bands are designated A-M, those of platypus A-G. Some of the proteins are isolated and characterized. 2. Echidna band A protein has some similarity to high cystine "whey" proteins. Band E protein (apparent Mr 21,000) may be a beta-lactoglobulin-like protein. Band M is lysozyme. Band C is serum albumin. Bands G-K are transferrins. 3. Platypus milk bands A, C, D, F and G are isolated. Bands F and G are transferrins. 4. Lactose synthase and lytic activities are examined.
