COMP (Cartilage Oligomeric Matrix Protein Precursor, EDM1, EPD1, Epiphyseal Dysplasia 1, Epiphyseal Dysplasia 1 Multiple, MED, MGC13181, MGC149768, PSACH, Pseudoachondroplasia, THBS5, Thrombospondin 5)
Description:
Cartilage Oligomeric Matrix Protein (COMP), also known as Thrombospondin-5, is a 110kD modular matricellular protein. COMP contains a non-collagenous coiled-coil domain, four EGF-like repeats, seven TSP type-3 repeats, and a globular TSP C-terminal domain. The coiled coil domain mediates the association of COMP into disulfide-linked homopentamers. An RGD sequence in the third TSP type-3 repeat mediates chondrocyte attachment via integrins alpha5beta1 and alphaVbeta3. COMP is upregulated in inflammation and some carcinomas.

Applications:
Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.

Recommended Dilution:
Western Blot: 2ug/ml detects human COMP in cell or tissue extracts.
Immunoprecipitation: 25ug/ml immunoprecipitates recombinant human COMP from conditioned cell culture media.
Optimal dilutions to be determined by the researcher.

Western Blot Buffers:
Blotting Buffer: 25mM Tris, pH 7.4, 0.15M sodium chloride, 0.05% Tween-20
