Several hundred polypeptides from four human diploid fibroblast cell lines were compared by high-resolution two-dimensional polyacrylamide gel electrophoresis and double-label autoradiography under conditions where allelic products that differ by a single charged amino acid would be distinguished. The average heterozygosity represented by this set of gene products appears to be less than 1% for changes involving charged amino acids.
在能够区分仅因一个带电荷氨基酸不同的等位基因产物的条件下，通过高分辨率二维聚丙烯酰胺凝胶电泳和双标记放射自显影技术，对来自四个人二倍体成纤维细胞系的数百种多肽进行了比较。对于涉及带电荷氨基酸的变化，这组基因产物所代表的平均杂合度似乎小于1%。
