| Résumé : |
Hides are prepared in the beamhouse for tanning by removing nonfibrous proteins from among the collagen fibrils. We now know that some of this proteins also contains type of collagen that do not form fibrils. This material might be expected to resist the drastic chemical treatments of the beamhouse, as does the collagen type 1 of the fibers. Using immunochemical stains, we have examined the persistence of two such nonfibrillar collagens, types 6 and 12, through simulatedliming, bating (trypsin digestion), and pickling. Both collagens persisted after treatment with lime, but the antigenic site on the molecule of the collagen type 12 was removed by trypsin. Collagen type 6 resisted all the treatments. Beamhouse treatments eliminate at least part of the type 12 molecule, which is found on the surfaces of the fibrils, but leaves type 6, which is present in very fine strands that connect the fibrils of type 1/3/5. These remnant proteins can complicate the use of syntans, fatliquors, and dyes, which act on the surfaces of the fibrils. |
