title: Large scale purification and further characterization of a rat liver cell conditioned medium multiplication stimulating activity.
abstract: The application of roller-bottle cell culture techniques and a relatively simple purification scheme has led to the isolation of milligram quantities of a polypeptide cell multiplication stimulating activity (MSA) from Buffalo rat liver cell conditioned medium. We have characterized the apparently homogeneous MSA with respect to its biological activity, its N-terminal amino acid residue, and its amino acid composition, and have tested the MSA for growth-promoting activity in a number of cell types.
