Protein Synthesis in the Hair Follicle. I. Extraction and Partial Characterization of Follicle Proteins**From the Department of Biochemistry, University of Adelaide, Adelaide, S.A., 5000, Australia.

The effects of various conditions for extracting hair follicle proteins by a modified wax-sheet technique were studied with reference to the yields and electrophoretic mobilities of the proteins obtained from different tissue preparations. Proteins were extracted more readily from dispersed hair-roots on wax-sheets than from intact hair-root suspensions. Dilute salt solutions and urea solubilized the same groups of follicle proteins, estimated by starch-gel electrophoresis, although the yields were less with the former
