Abcam’s DKK3 (Dickkopf-3) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human DKK3 in serum, plasma, and cell culture supernatants.
This assay employs an antibody specific for Human DKK3 coated on a 96-well plate. Standards and samples are pipetted into the wells and DKK3 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human DKK3 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 DKK3 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Optimisation may be required with urine samples.
Storage instructionsStore at -20°C. Please refer to protocols.

RelevanceDKK3, like DKK1, DKK2, and DKK4, possesses an N terminal signal peptide and 2 conserved cysteine rich domains, which are separated by a linker region and contain 10 cysteine residues each. The second cysteine region has a putative lipid binding function that may facilitate WNT/DKK interactions at the plasma membrane. The linker region contains 50 to 55 amino acids in DKK1, DKK2, and DKK4, whereas in DKK3 it contains only 12 amino acids. All DKKs have several potential sites for cleavage by furin type proteases.
