Maspin (mammary serine protease inhibitor) is a non-inhibitory serpin that is expressed predominantly in normal mammary epithelial cells but at significantly reduced levels or absent in most breast carcinomas. It has the ability to block the growth, invasiveness, and metastatic potential of breast and lung tumors. This anti-tumor activity is achieved, in part, by the ability of Maspin to inhibit angiogenesis and to preferentially promote apoptosis of tumor cells. Recombinant human Maspin is a 42.2 kDa non-glycosylated protein containing 375 amino acid residues.
The lyophilized Maspin recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted Maspin is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing Maspin recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
