表皮生长因子受体(EGFR)是一种分子量为170kd位于细胞膜表面的糖蛋白,能与生长因子结合而致细胞增生和分化。目前,对EGFR在人良、恶性组织中的表达,报道不一。本实验以抗EGFR的单克隆抗体 Epidermal Growth Factor Receptor (EGFR) is a glycoprotein with a molecular weight of 170 kd located on the surface of cell membranes, which can bind to growth factors and cause cell proliferation and differentiation. At present, there are different reports on the expression of EGFR in human benign and malignant tissues. This experiment uses monoclonal antibodies against EGFR
