| autoradiographic demonstration of inhomogeneous distribution of sodium in single oocytes of bufo bufo. | 1. autoradiography of frozen cells labelled with (22)na has been used to locate a sequestered fraction of internal na in the oocyte which exchanges very slowly or not at all with external li.2. relative grain density in nucleus and cytoplasm, measured photometrically, was used as an indication of (22)na distribution within the oocyte. in test experiments grain density fell to 50% within 19 mum of the edge of the section. owing to the large diameter of the oocyte (> 600 mum) and its nucleus (> 20 ... | 1970 | 5501264 |
