Comparative biochemical analysis reveals structural determinants of mobility across 91 mutant hemoglobins, highlighting improved identification of hemoglobinopathies.

Key Points

To assess how the molecular structure of 91 mutant hemoglobins influences their electrophoretic mobility in citrate agar compared to other electrophoretic techniques.
Assessed comparative mobilities of 91 mutant hemoglobins using citrate agar electrophoresis.
Correlated observed migration patterns with specific molecular features, including the helical positions of substituted amino acid residues, and compared them against other electrophoretic methods.
Mobility differed from normal adult hemoglobin (Hb A) in 11 of 27 alpha chain mutants (>33%) and 29 of 55 beta chain mutants (52.7%).
The helical location of amino acid substitutions represents a primary driver of electrophoretic mobility, governed by complex inter-residue interactions.
Integrating citrate agar mobility data with other electrophoretic profiles enables presumptive or definitive identification of specific hemoglobin variants and hemoglobinopathies.
