Two-step purification and N-terminal amino acid sequence analysis of the rat Mr 90,000 heat shock protein.
A fast and efficient method for the isolation of the rat Mr approximately 90,000 heat shock protein is presented, comprising a two-step high-performance anion-exchange and gel-permeation column chromatography. The Mr approximately 90,000 protein was purified to electrophoretic homogeneity in high yield (up to 2 mg per 10g of normal rat liver) in 4-5 h. The purified protein was recognized on protein immunoblots by monospecific rabbit antibodies raised against the rat glucocorticoid receptor-associated Mr approximately 90,000 non-ligand-binding protein. The N-terminal sequence of the first 25 amino acids of the purified protein showed a high degree of similarity with Mr approximately 90,000 heat shock proteins from calf, human, Drosophila, and yeast.
