摘要：
1. 1. Two distinct isoforms of tropomyosin, 32K and 30K components, were detected in a tropomyosin fraction prepared from eggs of the sea urchin. Strongylocentrotus intermedius, and some biochemical properties of these isoforms were investigated. 2. 2. The 32K component reacted strongly with the antisera raised to sea urchin muscle tropomyosin, whereas the 30K component showed only a very weak cross-reactivity with these antisera. 3. 3. The 32K component seemed to have a slightly higher actin-binding ability than the 30K component. © 1990.
