Clinical Applications:

This urine assay measures collagen TYPE II degradation, which may allow researchers to monitor the progression of collagen II-degradation related arthritis such as Osteoarthritis (OA) and Rheumatoid Arthritis (RA). C2C-HUSA


Enzymes known as Matrix Mettalloproteinases or MMPs (1,8,13) cleave Type l and ll collagen (bone and cartilage, respectively) to form degradation fragments.

Degradation fragments  containing the C-terminal NEOEPITOPE at the 3/4 length type II collagen (called C2C neoepitope or in short, C2C) can be detected by IBEX immunoassays, C1–2C and C2C.  C2C in human urine samples may be determined using IB-C2C-HUSATM
