A Schematic diagram of urea-based tECM extraction. B SDS-PAGE showed that tECM contains abundant low to medium molecular weight proteins that are absent in commercial collagen type I preparation (Col1). C Collagen content analysis (hydroxyproline assay calibrated with collagen type I standards) showed that the average collagen content was 246.32 μg/mL in a 1 mg/mL tECM solutionBack to article page
