Immunochemical comparisons of proteins that bind heme and bilirubin: human serum albumin, alpha-fetoprotein and glutathione S-transferases from liver, placenta and erythrocyte

1. Antisera to native or unfolded glutathione S-transferase from human liver recognize either antigen but do not recognize native or unfolded glutathione S-transferase from human placenta. 2. Antisera to native or unfolded glutathione S-transferase from placenta recognize either antigen but do not recognize native or unfolded glutathione S-transferase from liver. 3. Antisera to unfolded human serum albumin crossreacts with unfolded alpha-fetoprotein but does not recognize unfolded glutathione S-transferase.
