three sets of interindividually varying keratins could be distinguished owing to their distinct , though small , differences in electrophoretic mobility on sodium dodecyl sulfate-polyacrylamide gels and their similar or identical charge characteristics upon nonequilibrium ph gradient electrophoresis : the basic keratins 1a and 1b as well as 5a and 5b and the acidic keratins 10a and 10b .
