Abstract: | By means of indirect immunofluorescence techniques, distinct sea urchin antigens were localized in eggs and embryos (Paracentrotus lividus). The specificity of the method was ascertained from controls in which the specific rabbit anti-sea-urchin sera were substituted by rabbit antiserum to an unrelated antigen (human serum albumin), by normal rabbit serum or by phosphate-buffered saline. The specificity of staining was also evaluated by comparing the different staining patterns obtained either with antisera to whole homogenates of eggs and embryos or with antisera to distinct antigens. |
