StorageThe shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20˚C/-80˚C. The shelf life of lyophilized form is 12 months at -20˚C/-80˚C.
Application Details
Greater than 90% as determined by SDS-PAGE.

Background
Has weak activities on human monocytes and acts via receptors that also recognize MIP-1 alpha. It induced intracellular Ca2+ changes and enzyme release, but no chotaxis, at concentrations of 100-1,000 nM, and was inactive on T-lymphocytes, neutrophils, and eosinophil leukocytes. Enhances the proliferation of CD34 myeloid progenitor cells. The processed form HCC-1(9-74) is a chotactic factor that attracts monocytes eosinophils, and T-cells and is a ligand for CCR1, CCR3 and CCR5.
