Method for preparation of nephritogenoside.

摘要

In a method for preparing nephritogenoside from human placenta, rat kidney or other organs, tissues containing many microvessels are excised from the organ and treated with a nonionic surface active agent, especially, Triton X 100. Thus obtained precipitates are digested with trypsin and subjected to a chromatography treatment. Introduction of the nonionic surface active agent treatment enables simplification of the digestion step as well as a drastic improvement in yield.
