Abstract:
Collagen was prepared from common minke whale unesu and characterised. The yield of collagen was high, about 28.4% on a wet weight basis. By SDS-PAGE and CM-Toyopearl 650M column chromatography, the collagen was classified as type I collagen. The denaturation temperature of the collagen was 31.5°C, about 6-7°C lower than that of porcine collagen. Attenuated total reflectance-FTIR analysis indicated that acid-soluble collagen from common minke whale unesu held its triple helical structure well, but the structures of porcine skin collagen and pepsin-solubilized collagen from common minke whale unesu were changed slightly, due to the loss of N- and C-terminus domains.
