Highly-expressed S100A3, a calcium-binding protein, in human hair cuticle
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1996 Analyses on sodium dodecyl sulfate-polyacrylamide gel electrophoreses showed that the human hair cuticle extracts mainly consist of a 7-kDa component and keratin proteins. The S-carboxymethylation of the cuticle extracts made the 7-kDa band shift to the 15-kDa position.
