title: A mitogenic factor from rat muscle.
abstract: A growth-promoting polypeptide has been purified about 1950-fold from rat abdominal muscle by gel chromatography, isoelectric-focusing (IEF) and reverse phase high pressure liquid chromatographic (RP-HPLC) techniques. This factor is an acidic protein with an isoelectric point (pI) of 3.4 and a mol. wt of 12 kDa when run on SDS-polyacrylamide gels under reducing conditions. It is acid and heat-stable but is sensitive to reducing agent and protease action. It stimulates [3H]thymidine incorporation in NRK-49F and NIH 3T3 cells and induces soft agar colony formation of NIH 3T3 cells. The muscle-derived mitogen appears to differ from other known growth factors (GFs) in its physico-chemical properties.
