Elaunin fibres in the basement membrane of sweat gland secretory coil are rich in disulfide-groups.
Disulfide-groups of elaunin fibres of sweat gland basement membrane are demonstrated a) by thiosulfation/aldehyde-fuchsin staining or thiosulfation/Alcian Blue + 0.8 M MgCl2 staining, and b) by identifying SH-groups after reduction with sodiumthioglycollate. Elaunin fibres share this staining behaviour with "elastic fibre microfibrils" and with oxytalan fibres.
