Application: The assay is used for the measurement of total collagen. This includes all procollagen, unfolded collagen, mature collagen as well as collagen degradation products of all collagen types present in the sample. Since the first step is complete hydrolysis of the sample, difficulty in extraction of collagen plays no role. The assay is applicable for all types of samples, including tissue.

Also available in 5x 96-assays bulk pack (QZBtotcol5)

If you already have a hydrolysis protocol, the Hydroxyproline Assay Kit (link).

The Total Collagen assay kit is based on the quantitative colorimetric determination of hydroxyproline residues, obtained by acid hydrolysis of collagen. Usually for this analysis upon hydrolysis removal of HCl is needed, which is a time-consuming step and / or needs special equipment. The QuickZyme Total Collagen assay is the only hydroxyproline-based assay which does not need this laborious step, resulting in a fast (<2 hrs) and easy (96-well plate format) assay following the hydrolysis step.
