Keratins and keratin-associated protein levels in the cross-linked proteome. (a and b) Epidermal scale and cornified material were analyzed from three TAM67-positive and three TAM67-negative mice. Samples were processed for mass spectrometry as outlined in Materials and Methods.8 The values are weighted spectral counts shown as the mean±S.D.69 The asterisks indicate a significant difference (P<0.001, n=3)
