UnconditionalLovebyC The proteomics of keratin proteins. Application of K31 to the chemically damaged hairs resulted in increase of mechanical strength more than twice to 26N. It appears that keratin K31, the major protein lost in the damaged hair [11], gets integrated in to the damaged hair filling the gaps and thus enhancing their elasticity and mechanical strength. Bodybuilding And Hair Loss: Myth or Reality. The hair samples were attached into a pair of cardboard frames Centre with internal rectangular cut frame of 9045mm following the longest direction [24]. The K31 treatment of the damaged hairs showed young modulus score of 12,256N/mm2, which is almost 2 fold higher as compared to that of the chemically damaged hair. E. coli DH5 was used for cloning and vector propagation and E. coli BL21 CodonPlus (RIL) was used for the gene expression. Diameter of the hairs before and after treatment with K31 was measured by inverted microscope (Nikon Eclipse TS 100). Hair thickness, Youngs modulus, and breaking force values for the undamaged, chemically damaged and the keratin treated hairs.
