海胆（heliocidaris tuberculata）发育典型，形成棘状体（echinoid pluteus）幼虫。红革虫通过高度修饰的非食性幼虫直接发育。利用从紫癜性强心梗虫（stronglyocentrus purpuratus）中制备的卵黄糖蛋白多克隆抗体，我们发现。结核菌中含有大量的交叉反应蛋白，但th。erythrogrammadoes不是。此外，我们用免疫电镜证实了h。结核菌含有卵黄血小板，但h。erythrogrammado不是。
The sea urchinHeliocidaris tuberculataundergoes typical development, forming an echinoid pluteus larva, whereasH. erythrogrammaundergoes direct development via a highly modified, nonfeeding larva. Using a polyclonal antibody prepared against yolk glycoproteins from the typical developerStronglyocentrotus purpuratus, we found thatH. tuberculatacontains cross-reactive proteins in abundance, butH. erythrogrammadoes not. In addition, we used immunoelectron microscopy to demonstrate that unfertilized eggs ofH. tuberculatacontain yolk platelets, but those ofH. erythrogrammado not.
