重組人白介素3 Recombinant Human IL-3 (Animal-Free)

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).

溶解建議 提供的人Epigen因子（EPGN）產(chǎn)品為過濾滅菌的白色凍干粉末；該凍干粉末是從含人Epigen因子（EPGN）的20mM PBS緩沖液（pH 7。4），130mM NaCl溶液中凍干產(chǎn)生的。我們建議加無菌的18MΩ-cm水以配制工作儲(chǔ)存液到100ug/ml，后繼實(shí)驗(yàn)過程中可根據(jù)實(shí)驗(yàn)要求進(jìn)一步稀釋。

?

保存建議 人Epigen因子（EPGN）凍干粉末在室溫可保存3周，或置于-18℃凍存用于長期保存。重新溶解后可以在4℃冷藏保存至少2-7天以上；如果想延長保存時(shí)間，建議分裝（加載體蛋白如0。1% HSA或 BSA）后置于-18℃凍存。請避免反復(fù)凍融。
