Human C-telopeptide of Collagen alpha-1 (II)chain (CTXII) ELISA Kit

Manufactured by Assay Genie, this ELISA kit is designed for the quantitative measurement of human C-telopeptide of Collagen alpha-1 (II) chain (CTXII) in serum, plasma, tissue homogenates, cell culture supernates and other biological fluids. CTXII is a key marker of collagen type II degradation, associated with conditions such as osteoarthritis and cartilage degradation, making the kit useful in musculoskeletal research and joint health studies. The assay shows specificity for natural and recombinant human C-telopeptide of Collagen alpha-1(II) chain and is intended for research use only.

Reported performance characteristics include a detection range of 78–5000 pg/mL and a sensitivity of 32 pg/mL. Intra-assay CV is 4.3% and inter-assay CV is 7.5%. Average recovery is 100% (range 94–106%) in serum and 102% (range 96–108%) in plasma. Linearity in serum is reported as 89–116%, in EDTA plasma 95–119%, and in heparin plasma 91–117% across serial two-fold dilutions. The assay is read at 450 nm using a microplate reader. Reagent components are stored at -20°C or 4°C, and the product is shipped at +4°C.
