Figure 3. Sulfhydryl modification of bovine keratins.

Figure 3

A pool of k1/10 and 5/14, isolated from bovine snout, were treated with the sulfhydryl specific reagent CE-MTS. Panel A shows a representative view of kIFs assembled from the modified keratin proteins. Panel B shows CE-MTS treated proteins kIFs assembled in the presence of DTT. Panel C shows kIFs assembled from a 1:1 mixture of CE-MTS treated and untreated bovine keratins. Panel D is a 90:10 mixture of unmodified keratins to modified keratins, respectively. The scale bar located in the bottom of each panel represents 200 nm.
