血管内皮细胞生长因子 (ｖａｓｃｕｌａｒｅｎｄｏｔｈｅｌｉａｌｇｒｏｗｔｈｆａｃ ｔｏｒ,ＶＥＧＦ)是近年发现的一种促血管生长因子 ,其相对分子质量 (Ｍｒ)为 3.5× 10 4～ 4.5× 10 4属于糖蛋白 ,由两个Ｍｒ为 1.7× 10 4～ 2 .2× 10 4相同的亚单位经二硫键形成二聚体[1
Vascularendothelial growth factor (VEGF) is a kind of pro-angiogenic growth factor found in recent years. Its relative molecular mass (Mr) is 3.5 × 10 4 ~4.5 × 10 4 and belongs to glycoprotein. 10 4 ~ 2 .2 × 10 4 the same subunit disulfide bond to form dimers [1
