Biomarker Analysis

The ORC is fully equipped to run any commercially available absorbance or fluorescence biomarker immunoassay in 96 or 384-well plate format using Molecular Devices SpecraMax 384 plus, microplate absorbance/transmittance reader, as well as a Gemini-XS Fluorometer.

Our lab has extensive experience with the following biomarker assays:

Detection of Cartilage Markers

  • Alcian Blue: Standardize measurement of 35S labeled proteoglycan complexes.

  • C1,C2: An assay to standardize the measurement of Types I and II collagen degradation.

  • CPII: An assay to measure type II collagen carboxy propeptide (C-propeptide).

  • CS-846: Measurement of Aggrecan Chondroitin Sulfate 846 Epitope.

  • Eq. Col 2 3/4 (CEQ): An assay to quantify equine specific Type II collagen, which has also been proven to work with canine fluid.

  • GAG DMMB: An assay for standardized measurement of glycosaminoglycans in biological fluids and/or tissues.

  • Prolagen-C: Measurement of C-Terminal propeptide Type-I collagen.

  • Pyd Assay: An assay to standardize measurement of pyridinoline crosslinks in serum and urine.

  • Pyrilinks-D: To standardize measurement of deoxypyridinoline crosslinks in urine.

  • TCA: Assay to measure 3H content in media or cartilage digested samples.

  • YKL-40: Assay for measurement of YKL-40, human cartilage glycoprotein 39, in serum.

Detection of Bone Markers

  • C1,2C: An assay to standardize measurement of Type I and II collagens (378 assay, MMP1 and MMP13).

  • Serum Cross Laps® (CTX): Assay for the quantification of degradation products of C-terminal telopeptides of Type-I collagen in serum and plasma.

Cytokine Assays

  • HIL-1ra: To standardize the measurement of interleukin 1 receptor antagonist concentrations in cell culture supernatant, serum and plasma.

  • IGF: To standardize the measurement of Insulin-like Growth Factor in Serum, Cell culture and plasma.

  • TGF-β: An assay to quantify measurement of Transforming Growth Factor-beta in serum, cell culture supernatant, plasma and urine.

  • TNF-alpha: An assay to quantify levels of Tumor Necrosis Factor-alpha in serum, plasma, synovial fluid and cell culture supernatant
