血小板生长因子(PDGF)是最常见的肽类调节因子之一,它是1974年才被识别的一种刺激结缔组织细胞生成的激素。近年来,随着研究的不断深入,人们对其特性及其与疾病的关系的认识也逐渐加深,本文就此作一些介绍。一、PDGF的理化特性血小板中包含有数种生长因子,但其促进有丝分裂的活力50%来自一种单一的蛋白(或蛋白族),即PDGF。用SDS聚丙烯酰胺胶电泳可将PDGF高纯度制品分为分子量为27000,28500,29000和31000的四 Platelet-derived growth factor (PDGF), one of the most common peptide regulators, was a hormone that stimulated connective tissue production in 1974. In recent years, with the deepening of the research, people’s understanding of their characteristics and their relationship with the disease has gradually deepened. This article gives some introduction. First, the physical and chemical properties of PDGF Platelet contains several growth factors, but its promotion of mitosis 50% of the activity from a single protein (or protein family), that PDGF. SDS polyacrylamide gel electrophoresis PDGF can be divided into high-purity products molecular weight of 27000,28500,29000 and 31000 of the four
