Abstract
  1. Using immunological methods, we have identified parvalbumin-like material in the triclade flatworms, Polycelis nigra, Polycelis auriculata, Crenobia alpina, Dugesia tahitiensis, and Dugesia polychroa. 2. Western immunoblot analysis of these five species revealed heat stable parvalbumin-immunoreactive proteins between 32 kD and 44 kD. 3. Proteins at 19 and 32 kD revealed intense labeling with 45Ca2+. 4. Double immunodiffusion of planarian supernatants showed complete fusion of precipitates, indicating immunological relatedness of the parvalbumin-like material among the species investigated. 5. Immunocytochemical studies exhibit parvalbumin-immunoreactive material exclusively in neurons supporting the notion of an early evolutionary appearance of these proteins in the nervous system.
摘要
  1. 我们利用免疫学方法,在三枝扁形虫(Polycelis nigra、Polycelis auriculata、Crenobia alpina、Dugesia tahitiensis和Dugesia polychroa)中鉴定出了类小白蛋白物质。2. 对这五个物种的蛋白质免疫印迹分析显示,在32 kD至44 kD之间存在热稳定的小白蛋白免疫反应性蛋白。3. 19 kD和32 kD的蛋白质显示出与45Ca2+的强烈结合。4. 涡虫上清液的双向免疫扩散显示沉淀物完全融合,表明在所研究的物种中类小白蛋白物质具有免疫相关性。5. 免疫细胞化学研究表明,小白蛋白免疫反应性物质仅存在于神经元中,支持了这些蛋白质在神经系统中早期进化出现的观点。
