Separation of native types I and III collagens and denatured chains by reverse-phase high-performance liquid chromatography.
A simple and effective high-performance-liquid-chromatography system has been developed for the separation of the native forms of Types I and III collagens. This separation is achieved on a commercially available 330-A-pore-size C18 reverse-phase support using a solvent system consisting of ammonium bicarbonate (0.05 M) and trifluoroacetic acid (0.4%) with tetrahydrofuran as the eluting solvent. This simple system can also be applied to the separation of mixtures of the denatured chains of both collagen types.
