  • Product overview

    Abcam’s Decorin (DCN) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human Decorin in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for Human Decorin coated on a 96-well plate. Standards and samples are pipetted into the wells and Decorin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti Human Decorin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Decorin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Function
    May affect the rate of fibrils formation.
  • Involvement in disease
    Defects in DCN are the cause of congenital stromal corneal dystrophy (CSCD) [MIM:610048]. Corneal dystrophies are inherited, bilateral, primary alterations of the cornea that are not associated with prior inflammation or secondary to systemic disease. Most show autosomal dominant inheritance.
  • Sequence similarities
    Belongs to the small leucine-rich proteoglycan (SLRP) family. SLRP class I subfamily.
    Contains 12 LRR (leucine-rich) repeats.
  • Post-translational
    The attached glycosaminoglycan chain can be either chondroitin sulfate or dermatan sulfate depending upon the tissue of origin.
  • Cellular localization

Decorin ELISA kit easy to use

Good Excellent 5/5 (Ease of Use)
It's very easy to use.
We tested this kit on pig wounded skin tissue.
We got acceptable result but we need more samples to statistics analysis.
