A new ?2HS-glycoprotein typing by isoelectric focusing

Abstract
Isoelectric focusing (pH 4.0–5.0) of serum α2HS-glycoprotein on polyacrylamide gels has been found to be a useful tool in population genetics and forensic science. Using this method, we isolated three common types, α2HS 1-1, α2HS 2-1 and α2HS 2-2, and showed that α2HS types are determined by two autosomal codominant alleles, α2 HS 1 and α2 HS 2. The method is simple, fast and easy to perform. Results of typing for the two alleles, α2 HS 1 and α2 HS 2, are described for a Japanese population sample (n=1003).
