Biocolor's enhanced soluble collagen assay — improved sensitivity and reduced interference compared with the original Sircol. Uses a convenient 96-well microplate format. A straightforward alternative to hydroxyproline analysis.
Down to 0.25 µg/ml (using optional concentration protocol).
Reformulated dye for a greater degree of dye–collagen specificity.
96 measurements — 41 samples in duplicate, plus a standard curve.
Biocolor kits appear in the methods of hundreds of peer-reviewed papers every year, from fibrosis drug discovery to cartilage repair, cardiovascular grafts and rare-disease trials.

Measuring collagen deposition in lung, heart, liver and skin fibrosis models, and screening antifibrotic drugs.
Tracking the sGAG that chondrocytes and stem cells build into engineered cartilage and disc.
Showing how much collagen, sGAG and elastin a matrix keeps after decellularisation.
Elastin and collagen in arteries, valves, plaques and regenerating vascular grafts.
Collagen and elastin made in response to wound therapies and cosmetic actives.
GAGs and collagen in inherited disorders, from MPS clinical research to osteogenesis imperfecta.
Assay feature
Designed to simplify quantification so you can focus on your research. Every kit ships with a QuickStart Guide, a detailed Assay Manual and a Certificate of Analysis.

We specialise in dye-based detection reagents, formulated to label each specific biomolecule and give a robust, reproducible binding response.
Assay feature
Colorimetric detection throughout, so dye-labelled biomolecules are read on a standard spectrophotometer — no specialist instruments required.
Assay support
Individual support by email or phone, answered by the people who make the kits. We like hearing how our kits are used!
