Immunochemical properties of abnormal hemoglobins C-Harlem (beta 6 Glu replaced by Val, beta 73 Asp replaced by Asn), S (beta 6 Glu replaced by Val), Korle Bu (beta 73 Asp replaced by Asn), Vancouver (beta 73 Asp replaced by Tyr), and Mobile (beta 73 Asp replaced by Val). 1980

Antibodies were made to three mutant hemoglobins, each containing different single amino acid substitutions at beta 73:Hb Korle Bu (Asp replaced by Asn), Hb Mobile (Asp leads to Val), Hb Vancouver (Asp replaced by Tyr); and to one mutant hemoglobin, Hb C-Harlem, containing two substitutions in the beta chain (beta 6 Glu replaced by Val, as in Hb S, and beta 73 Asp replaced by Asn, as in Hb Korle Bu). The antiserum to Hb C-Harlem contained two antibody populations, each specific for one mutant amino acid residue. The antiserum to Hb Vancouver was completely specific for this mutant and did not cross-react with Hb Mobile and Hb Korle Bu; however, antiserum to Hb Korle Bu partially cross-reacted with Hb Mobile and to a smaller degree with Hb Vancouver. Antiserum to Hb Mobile exhibited even less cross-reactivity with Hb Korle Bu and C-Harlem and none with Hb Vancouver. These and previous studies indicate the involvement of at least three independent areas in the beta chain as antigenic determinant sites. It appears that the three mutants at beta 73 elicit the formation of antibodies which have a gradation in their specificity due to the nature of the amino acid sidechain.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays

D006444 Hemoglobin C A commonly occurring abnormal hemoglobin in which lysine replaces a glutamic acid residue at the sixth position of the beta chains. It results in reduced plasticity of erythrocytes.
D006455 Hemoglobins, Abnormal Hemoglobins characterized by structural alterations within the molecule. The alteration can be either absence, addition or substitution of one or more amino acids in the globin part of the molecule at selected positions in the polypeptide chains. Abnormal Hemoglobins
