Chromatograms of size-exclusion chromatography (SEC) of supernatants collected at a wavelength of 210 nm. (a) C-coll hydrogel in Tris buffer, pH 7.4 (CB); (b) D-coll hydrogel in Tris buffer, pH 7.4 (DB); (c) C-coll hydrogel in collagenase solution in Tris buffer, pH 7.4 (CC) and (d) D-coll hydrogel in collagenase solution in Tris buffer, pH 7.4 (DC). Peaks are labelled as: β = collagen β chains; α = collagen α chains; LHP = low molecular weight hydrolyzed peptides; AcOH = acetic acid; AA = amino acids.
