 血管内皮生长因子（Vascular endothelial growth factor，VEGF）又称血管通透因子（Vascular permeability factor，VPF），是胎儿和成人血管发生和血管生成过程中重要的调控因子。VEGF是特异性作用于内皮细胞的糖基化细胞有丝分裂素，在增强血管的渗透性、诱导血管发生和血管生成及内皮细胞生长、促进细胞迁移、抑制细胞凋亡等方面发挥作用。由于mRNA不同的剪切方式，产生了VEGF121、VEGF145、VEGF165、VEGF183、VEGF189和VEGF206等6种蛋白形式。VEGF165是人类组织中VEGF主要的基因产物，也是VEGF家族中最重要的血管生成调节因子。

Recombinant Human IL-4

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.
