Human Angiopoietin 2 ELISA Kit

Reactivity:Human, Product range:8-150 pg/ml, Storage:Store at 2-8?C for 6 months, Target:Angiopoietin 2, Sample type:Serum, plasma, urine, cell culture supernatants, and tissue samples, Principle assay:This Angiopoietin 2 enzyme linked immunosorbent assay (ELISA) applies a technique called a quantitative sandwich immunoassay. The microtiter plate has been pre-coated with an Anti-Angiopoietin 2 Antibody. Standards or samples are then added to the microtire plate wells and Angiopoietin 2, if present, will bind to the antibody pre-coated on the wells. In order to quantify the amount of Angiopoietin 2 present in the sample, Anti-Angiopoietin 2 Antibody (HRP) is added to each well to “sandwich” the Angiopoietin 2 immobilised on the plate. The microtiter plate then undergoes incubation, followed by thorough washing of the wells to remove all unbound components. Next, a TMB (3,3′,5,5′ tetramethyl-benzidine) substrate solution is added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain Angiopoietin 2 will exhibit a change in colour. The enzyme-substrate reaction is terminated by the addition of a stop solution and the colour change is measured spectrophotometrically at a wavelength of 450nm ? 2nm, Assay type:Sandwich (quantitative), Detection type:Colorimetric, Platform:Microplate
