Rat DEFb2 (Defensin Beta 2) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat DEFb2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat DEFb2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat DEFb2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat DEFb2 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 15.63-1000 pg/mL. Sensitivity: 5.3 pg/mL. Assay Type: Sandwich. Standard: 1000 pg/mL. Sample Type: sserum, plasma, tissue homogenates, cell lysates and other biological fluids. Assay duration: 3.5h. Protein Function: Exhibits antimicrobial activity against Gram-negative bacteria and Gram-positive bacteria. May act as a ligand for C-C chemokine receptor CCR6. Binds to CCR6 and induces chemotactic activity of CCR6-expressing cells [The Uniprot Consortium]
