Rabbit antisera to homogenates of unfertilized sea urchin eggs were absorbed with pluteus extract. In the same way, antisera to gastrulae or plutei were also made. "stage specific" by absorption with extracts of eggs. When tested by means of immunoelectrophoresis the absorbed sera formed precipitate

Eggs and developmental stages of the sea urchin Paracentrotus lividus were incubated with radioactive (14C) amino acids. Incorporation of label into antigen was studied by means of rabbit antisera against sea urchin material. In an attempt to block genetic control of protein synthesis, eggs and embr
The relationship between heterogeneous nuclear RNA (hnRNA) and messenger RNA (mRNA) synthesis has been studied as a function of the development of the sea urchin embryo through the use of methyl incorporation. Several parameters in the metabolism of capped hnRNA and mRNA of early blastula and late g
## Abstract We describe a new RNA binding protein from __Xenopus__ we have named ePABP2 (embryonic poly(A) binding protein type II). Based on amino acid similarity, ePABP2 is closely related to the ubiquitously expressed nuclear PABP2 protein that directs the elongation of mRNA poly(A) tails during
