Maspin is a non-inhibitory member of the serpin superfamily, a group of 40-60 kDa serine protease inhibitors. Maspin was discovered in 1994 and has been identified in prostate, thymus, testis, intestine, tongue, and lung. Recently Maspin received a great deal of attention due to its potential apoptotic role in cancers. Maspin expression predicts a better prognosis for several types of carcinomas including breast, prostate, colon, and oral squamus cell carcinoma. The level of Maspin is also inversely correlated to VEGF-A, an angiogenic factor. Researchers found that Maspin may play its apoptotic role as an endogenous inhibitor of histone deacetylase I (HDAC I). Therefore, Maspin is a potential personalized marker of Non-Small Cell Lung Carcinoma (NSCLC).

Recombinant human Maspin (rhMaspin) produced in E. coli is a single non-glycosylated polypeptide chain containing 375 amino acids. rhMaspin has a molecular mass of 42.1 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.

溶解建议 提供的人Epigen因子（EPGN）产品为过滤灭菌的白色冻干粉末；该冻干粉末是从含人Epigen因子（EPGN）的20mM PBS缓冲液（pH 7。4），130mM NaCl溶液中冻干产生的。我们建议加无菌的18MΩ-cm水以配制工作储存液到100ug/ml，后继实验过程中可根据实验要求进一步稀释。

保存建议 人Epigen因子（EPGN）冻干粉末在室温可保存3周，或置于-18℃冻存用于长期保存。重新溶解后可以在4℃冷藏保存至少2-7天以上；如果想延长保存时间，建议分装（加载体蛋白如0。1% HSA或 BSA）后置于-18℃冻存。请避免反复冻融。
