Avian feather keratins: Molecular aspects of structural heterogeneity
Abstract Solubilized SCM‐Keratins from feathers of a tern ( Sterna hirundo ) and turkey ( Meleagris gallopavo ) were fractionated by gel‐filtration and ion‐exchange chromatography. Tryptic peptide maps were prepared and amino‐acid compositions determined. Subsequent comparison indicated that within...
