Preparation and Storage
Background: COMP/Thrombospondin-5
COMP (Cartilage Oligomeric Matrix Protein), also known as Thrombospondin-5, is a multidomain calcium binding protein that associates with other extracellular matrix molecules. COMP associates into disulfide-linked homopentamers with a central hub and peripheral globular domains connected by flexible strands. An axial pore is formed by the coiled coil assembly and binds vitamin D3 which is involved in bone and cartilage metabolism. An RGD sequence in the third TSP type-3 repeat mediates chondrocyte attachment via Integrins a5b1 or aVb3. COMP is upregulated in rheumatoid arthritis and osteoarthritis, hepatocellular carcinomas, chronic pancreatitis, and pancreatic carcinomas. Several mutations in COMP are associated with skeletal dysplasias.
Assay Procedure
Refer to the product- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 100 µL of Assay Diluent to each well.
- Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
- Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
- Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
- Aspirate and wash 4 times.
- Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
- Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
