Group-specific component (Gc) and transferrin (Tf) subtypes ascertained by isoelectric focusing

Abstract

Simultaneous subtyping of Gc and TfC by isoelectric focusing allows us to compute the following gene frequencies for the Belgian population: $$\begin{gathered} Gc^{1{\text{S}}} = 0.543 Gc^{1{\text{F}}} = 0.167 Gc^{\text{2}} = 0.290 \hfill \\ \hfill \\ \hfill \\ Tf^{{\text{C1}}} = 0.784 Tf^{{\text{C2}}} = 0.206 Tf^{\text{B}} = 0.007 Tf^{\text{D}} = 0.003 \hfill \\ \end{gathered} $$ The Gc bands were precipitated by sulfosalicylic acid instead of by immunofixation.
