Collagen origin and processing affects polymerization kinetics. Polymerization kinetics of “in house” extracted porcine skin collagen (PSC) extracted using acid compared to commercially sourced acid solubilized bovine dermis (Sigma), acid solubilized rat tail (BD-RTC) and pepsin treated bovine dermis (PureCol) collagens. Collagen was polymerized at concentrations of 0.5 and 1.0 mg.ml (lower and upper curve for each collagen source, respectively) and measured spectrophotometrically at 405 nm.
