Structure and Performance of Cuticles Isolated from Wool Fibers Using Different Approaches.

Besides, the cuticle-L + U lane showed a lighter blue band than that of the raw wool and cuticle-FA, indicating the cuticle-L + U was more difficult to be dissolved than cuticle-FA.

FT-IR spectrum of the raw wool, cuticle-FA, and cuticle-L + U FTIR spectra comparison between the raw wool, cuticle-FA, and cuticle-L + U showed differences in 1200-1000 cm SP -1 sp . SDS-PAGE analysis of the raw wool (Lane 1), cuticle-FA (Lane 2), cuticle-L + U (Lane 3) Conclusion Taken together, our data demonstrated that pure and flaky-shaped cuticle cells could be effectively isolated with the L-cysteine and formic acid methods, respectively.
