前列腺特异性抗原 (ＰＳＡ)是由前列腺上皮细胞分泌的糖蛋白 ,相对分子质量 330 0 0 ,具有组织特异性[1 ] ,被认为是目前检测前列腺癌最好的肿瘤标志物。ＰＳＡ免疫组化方法检测前列腺癌具有特异性好、灵敏度高等优点 ,临床上广泛应用于对前列腺癌的诊断和鉴别诊断。我们在多年
Prostate-specific antigen (PSA), a glycoprotein secreted by prostate epithelial cells, has a tissue-specific molecular weight of 330,000 and is considered to be the best tumor marker for the detection of prostate cancer. PSA immunohistochemical detection of prostate cancer has good specificity, high sensitivity, clinical widely used in the diagnosis and differential diagnosis of prostate cancer. We are for many years
