Assay Principle
This EZ-Set™ kit supplies a matched capture and detection antibody pair and a standard for building your own sandwich ELISA for human aggrecan core protein (gene ACAN) in cell culture supernatants, serum and urine. You coat the plate with the capture antibody, add samples and standards, detect with the biotinylated antibody and an avidin–biotin–peroxidase complex, develop with TMB and read at 450 nm. Plates, diluents, wash buffer, TMB and stop solution are not included.
Aggrecan (ACAN) is a large proteoglycan and a major structural component of cartilage. Its many chondroitin and keratan sulfate chains attract water, and it binds hyaluronan to form aggregates that let cartilage resist compression, so its loss is a central feature of osteoarthritis.
