Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B
Human Leptin is an 167aa residue, ~16kD, adipocyte derived, secreted protein. Human Leptin was cloned, expressed in E. coli and purified. The purity of Leptin is greater than 95% as determined by SDS-PAGE. The identity of protein has been confirmed by N-terminal sequence analyses. Endotoxin level in the final preparation is less than 1pg/ug of murine Leptin. Mouse leptin is about 85% homologous with human Leptin. Purified human Leptin has been shown to be biologically active in reducing body weight, food consumption, and plasma glucose levels in ob/ob and NZO mice.
