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.
Cited in the literature
Trusted at the bench, cited in the literature.
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.

How researchers are using 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.
Recent examples
Explore research using Biocolor kits →Sircol 2.0 & Fastin measurement of soluble collagen & elastin in Bruch's membrane, aiding development of an in vitro model of age-related macular degeneration.
Sircol measured soluble collagen in lung tissue from a fibrosis model, testing a candidate therapy designed to resolve lung inflammation and fibrosis.
Blyscan measured the GAG made by stem cells growing on new artificial-proteoglycan implants for cartilage repair.
