We create easy-to-use kits for Extracellular Matrix analysis
Dye-based colorimetric assays for quantifying collagen, elastin, sulfated glycosaminoglycans and hyaluronan — in tissue, cells and fluids, from in-vivo and in-vitro sources. Made in the United Kingdom, supplied worldwide through specialist distributors.

A simpler way to quantify soluble collagen.....
Introducing Sircol 2.0, 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.
Enhanced sensitivity
Down to 0.25 µg/ml (using optional concentration protocol).
Reduced interference
Reformulated dye for a greater degree of dye–collagen specificity.
Microplate convenience
96 measurements — 41 samples in duplicate, plus a standard curve.
Trusted by researchers worldwide
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.

Where researchers use Biocolor kits
Fibrosis research
Measuring collagen deposition in lung, heart, liver and skin fibrosis models, and screening antifibrotic drugs.
Cartilage & joint repair
Tracking the sGAG that chondrocytes and stem cells build into engineered cartilage and disc.
Decellularised tissues & scaffolds
Showing how much collagen, sGAG and elastin a matrix keeps after decellularisation.
Cardiovascular & vascular grafts
Elastin and collagen in arteries, valves, plaques and regenerating vascular grafts.
Skin, wound healing & cosmetics
Collagen and elastin made in response to wound therapies and cosmetic actives.
Rare genetic disease
GAGs and collagen in inherited disorders, from MPS clinical research to osteogenesis imperfecta.
