1295538-5	1992	The molecular weight of the translation product corresponding to the bovine PRL precursor was estimated to be approximately 25,000 by SDS polyacrylamide gel electrophoresis and autoradiograph.	polyacrylamide	138-152	prolactin	Bos taurus	76-79	
3514183-5	1986	Prolactin, a single-chain polypeptide of molecular weight 24,000, was identified by Coomassie Blue staining of NaDodSO4-polyacrylamide gels of total protein from transformed E. coli cells, and by reaction with specific antibody.	polyacrylamide	120-134	prolactin	Bos taurus	0-9	
4065147-2	1985	Native disulphide-bonded prolactin (band III) was distinguished from reduced prolactin (band II) and intermediate unstable disulphide-linked conformations by: (a) faster mobility of the former in sodium dodecyl sulphate/polyacrylamide gel electrophoresis, and (b) high-pressure liquid chromatography analyses of tryptic-digested peptides derived from prolactin in various conformations during its refolding pathway from reduced, unfolded to native conformation.	polyacrylamide	220-234	prolactin	Bos taurus	25-34
