Immunochemical identity of the high and low molecular weight forms of Galapagos marine iguana hemoglobin.
1. Two forms of Galapagos marine iguana methemoglobin, with molecular weights of 140,000 and 70,000 daltons, were identified in iguana RBC lysates by Sephadex G-200 molecular sieve fractionation. 2. The 140,000 dalton ferric hemoglobin was isolated by DEAE-Sephadex A-50 ion-exchange chromatography and found to be pure by electrophoretic and immunological criteria. 3. Immunochemical analyses revealed the high and low molecular weight hemoglobins to be antigenically identical.
