Duck lipopolysaccharide (LPS) ELISA kit, an enzyme-linked immunosorbent assay, has the ability to detect levels of duck LPS as low as 0.1 pg/mL and its detection range is 1.25-40 pg/mL.
Assay Principle
Duck lipopolysaccharide (LPS) ELISA kit is designed to measure the level of duck LPS in a sample. It utilizes purified duck LPS antibody to coat the microtiter plate wells, creating a solid-phase antibody. The sample is then added to the wells, allowing the Goat LBP to bind to the solid-phase antibody. HRP-labeled antibodies specific to duck LPS are subsequently added, forming an antibody-antigen-enzyme-antibody complex. After thorough washing, a TMB substrate solution is added, resulting in a blue color development due to the catalytic activity of the HRP enzyme. The reaction is stopped by adding a sulfuric acid solution, and the color change is measured at a wavelength of 450 nm using a spectrophotometer. The concentration of duck LPS in the samples is determined by comparing the absorbance (O.D.) of the samples to a standard curve.
