Obestatin BioAssay(TM) ELISA Kit (Human, Mouse, Rat)

Obestatin Enzyme Immunoassay (EIA) BioAssay(TM) Kit is an in vitro quantitative assay for detecting Obestatin peptide based on the principle of Competitive Enzyme Immunoassay. The microplate in the kit is pre-coated with anti-rabbit secondary antibody. After a blocking step and incubation of the plate with anti- Obestatin antibody, both biotinylated Obestatin peptide and peptide standard or targeted peptide in samples interacts competitively with the Obestatin antibody. Uncompeted (bound) biotinylated Obestatin peptide then interacts with Streptavidin-horseradish peroxidase (SAHRP), which catalyzes a color development reaction. The intensity of colorimetric signal is directly proportional to the amount of biotinylated peptide-SA-HRP complex and inversely proportional to the amount of Obestatin peptide in the standard or samples. This is due to the competitive binding to Obestatin antibody between biotinylated Obestatin peptide and peptides in standard or samples. A standard curve of known concentration of Obestatin peptide can be established and the concentration of Obestatin peptide in the samples can be calculated accordingly. The minimum detectable concentration of Obestatin is 0.1 pg/ml. \n\nSample Type:\nSerum, plasma and cell culture media etc.\n\nIntended Use:\nThe BioAssay(TM) kit is used for quantitative protein detection, establishing normal range and validation of antibody array results.\n\nSpecificity:\nThe capture antibody provided in this kit recognizes human, mouse and rat Obestatin. This EIA kit shows no cross-reactivity with the following cytokines tested: e.g., Ghrelin, Nesfatin, Angiotensin II, NPY and APC.\n\nSensitivity:\nThe intra-assay reproducibility is CV<10% and inter-assay is CV<12%. \n\nRange:\nThe detection range for the kit is 0.1-1000pg/ml. \n\nKit Components:\nObestatin Microplate (Item A), 1x96wells\nWash Buffer Concentrate (Item B), 1x25ml\nStandard Obestatin peptide (Item C), 2x vials\nAssay Diluent A (Item D), 1x30ml\nAssay Diluent B (Item E), 1x15 ml\nBiotinylated Obestatin peptide (Item F), 2x vials\nHRP-Streptavidin concentrate (Item G), 1x600ul\nTMB One-Step Substrate Reagent (Item H), 1x12ml\nStop Solution (Item I), 1x8ml\nPositive control (Item M), 1x vial\nAnti- Obestatin polyclonal antibody (Item N), 2x vials\n\nStorage and Stability:\nStore powder at 4 degrees C liquid at -20 degrees C.
