Form: lyophilized (MIA protein was lyophilized from a solution containing 20 mM Potassium phosphate pH 7.0 and 150 mM KCl)

MIA (Melanoma Inhibitory Activity Protein) acts as a potent tumor cell growth inhibitor for malignant melanoma cells and some other neuroectodermal tumors, including gliomas, in an autocrine fashion. In a study of human melanoma cell lines with different metastatic capacity MIA mRNA expression appeared to be inversely correlated with pigmentation. MIA has been shown to represent a very sensitive and specific serum marker for systemic malignant melanoma that might be useful for staging of primary melanomas, detection of progression from localized to metastatic disease during follow-up, and monitoring therapy of advanced melanomas. Recombinant human MIA produced in E. coli is a single, non-glycosylated, polypeptide chain consisting of 108 amino acids having a total molecular mass of 12.237 kDa. MIA was identified as an inhibitor of in vitro growth of malignant melanoma cells. The protein contains a SH3 domain. Human Melanoma Inhibitory protein is purified by proprietary chromatographic techniques.

Endotoxin: Less than 0.1 ng/μg (IEU/μg) of MIA.
