Human COMP / TSP5 ELISA Pair Set

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human COMP Materials provided
Capture Ab:0.5 mg/mL of mouse anti-COMP monoclonal antibody. Dilute to a working concentration of 2 μg/mL in CBS before coating.
Detection Ab:Each vial contains 120 μg biotinylated rabbit anti-COMP polyclonal antibody. Reconstitute with sterile 1 mL distilled water. Dilute to a working concentration of 2 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 60 ng of recombinant COMP. Reconstitute with 1 mL detection antibody dilution buffer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 2500 pg/mL is recommended.
Streptavidin-HRP:50 μL of streptavidin conjugated to horseradish-peroxidase. 1:2000 Dilution in detection antibody dilution buffer before use.
Human COMP Specificity
Human COMP Sensitivity
The minimum detectable dose of human COMP / TSP5 was determined to be approximately 39.1 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
Human COMP Principle of the product
The human COMP / TSP5 ELISA Pair Set is for the quantitative determination of human COMP.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for COMP /TSP5 coated on a 96-well plate. Standards and samples are added to the wells,and any COMP / TSP5 present binds to the immobilized antibody. The wells arewashed and a biotinylated rabbit anti-COMP polyclonal antibody is then added,producing an antibody-antigen-antibody "sandwich". To produces color inproportion to the amount of COMP / TSP5 present in the sample strepavidin-HRPand TMB substrate solution are loaded. The absorbances of the microwell areread at 450 nm.

COMP Background

Cartilage Oligomeric Matrix Protein (COMP), also referred to as Thrombospondin-5, is a non-collagenous extracellular matrix (ECM) protein and belongs to the subgroup B of the thrombospondin protein family. This protein is expressed primarily in cartilage, ligament, and tendon, and binds to other ECM proteins such as collagen I, II and IX with high affinities depending on the divalent cations Zn2+ or Ni2+. COMP is a secreted glycoprotein that is important for growth plate organization and function. It is suggested to play a role in cell growth and development, and recent studies have revealed the possible mechanism that it protects cells against death by elevating members of the IAP (inhibitor of apoptosis protein) family of survival proteins. Mutations in COMP cause two skeletal dysplasias, pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (EDM1), and up-regulated expression of COMP are observed in rheumatoid arthritis and certain carcinomas.
