摘要: The binding sites of membrane-bound receptors such as insulin, acetyl choline, concanavaline A (Con A) are clearly demonstrated with a radioactive isotope (hot RI) incubation after light fixation. This type autoradiography (ARG) visualizes the correct good morphological characteristics. For steroid hormones estrogen including vitamine D3, genomic receptor cannot be samples except essential specific strong affinity in special granules eosinophilic leucocytes. We 125I-insulin liver, red blood cells, and heart muscle; 125I-α-bungarotoxin (bungarotoxin) rat intercostal muscle motor end-plate, cerebellum, cerebrum; 125I- or 3H-Con on surface human cells; 3H-estradiol 3H-moxestrol leucocytes uterus.
