High performance gel permeation chromatography of proteins. Application to embryonic inducing factors.
Proteins in the molecular weight range of 10 000-170 000 were separated by high performance gel permeation chromatography. Silica particles with 30 nm or 50 nm pores were derivatized with glycidoxypropyltrimethoxysilane and used as support. The proteins were eluted with 50% formic acid. A protein fraction which induces endodermal and mesodermal tissues in amphibian gastrula ectoderm was purified by this method.
