1) Intercellular distribution of phosphoproteins in bovine parotid gland was studied, and the order of the amount of phosphoprotein in the subcellular fractions was nuclei> supernatant> microsomes> zymogen> mitochondria.
2) In the supernatant fraction of parotid gland, three kinds of phosphoproteins were identified using electrophoresis.
3) Two kinds of phosphoproteins were separated from the dried acetone powder of bovine parotid gland with borate buffer extraction and ammonium sulfate fractionation.
4) Borate buffer soluble phosphoproteins of acetone dried powder of parotid gland were partially purified using ammonium sulfate fraction and DEAE-cellulose column chromatography.
