Identification of Fib3-1 and Fib3-2 biomarkers

Fibulin 3 Peptides Fib3-1 and Fib3-2 Are Potential Biomarkers of Osteoarthritis
Thirteen proteins within spots that were significantly modified between groups were identified. Two peptides of fibulin 3, named Fib3-1 and Fib3-2, were of particular interest. Using area under the receiver operating characteristic curve analysis, we demonstrated that Fib3-1 and Fib3-2 levels discriminate between OA and normal populations.
