An attempt has been made to locate human placental lactogen (HPL) and human chorionic gonadotrophin (HCG) in cells within the human term placenta. Using immunoperoxidase techniques on frozen sections of tissue, no difference could be found between specific antisera and control sera. A theory is put forward that it may not be possible to visualize these hormones in the placenta using present immunoperoxidase techniques.
已尝试在足月人胎盘中的细胞内定位人胎盘催乳素(HPL)和人绒毛膜促性腺激素(HCG)。对组织冰冻切片采用免疫过氧化物酶技术,未发现特异性抗血清与对照血清之间存在差异。有人提出一种理论,即使用目前的免疫过氧化物酶技术可能无法在胎盘中观察到这些激素。
