Samples (liquid or solids) are analyzed in a cell based system to evaluate potential inducers of collagen Type 1 synthesis. This system utilizies Normal Human Dermal Fibroblasts and one ELISA kit specific for the Type 1 Procollagen peptide with the final readout being measured in ng/mL. Specific sample handling procedures can be generated for particular purposes with the analysis being performed either in a GLP / cGMP or R&D format. There is an additional charge for GLP and cGMP methods as compared to R&D projects.
