We found that, in contrast to earlier reports, inter-alpha-trypsin inhibitor of human serum is not a single-chain glycoprotein, but a protein complex. Three different protein components which are encoded on three independent mRNAs could be demonstrated by sequencing of cloned cDNA as well as of peptides obtained from purified inter-alpha-trypsin inhibitor… CONTINUE READING
