CD274 ELISA Kit (Human)

• Reproducibility :

  Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Programmed Cell Death Protein 1 Ligand 1 (PDL1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Programmed Cell Death Protein 1 Ligand 1 (PDL1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

• Gene ID :

  29126

• Accession Number :

  NP_001254635.1

• Reactivity :

  Homo sapiens|Human

• Target :

  Plays a critical role in induction and maintenance of immune tolerance to self. As a ligand for the inhibitory receptor PDCD1/CD279, modulates the activation threshold of T-cells and limits T-cell effector response (PubMed:11015443) . The PDCD1/CD279-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and facilitate tumor survival (PubMed:28813417, PubMed:28813410) . Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10) (PubMed:10581077) .

• Type :

  ELISA Kit

• Applications :

  Enzyme-linked Immunosorbent assay-Sandwich

• Detection Method :

  Colorimetric

• Assay Principle :

  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 Programmed Cell Death Protein 1 Ligand 1 (PDL1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Programmed Cell Death Protein 1 Ligand 1 (PDL1) . 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 Programmed Cell Death Protein 1 Ligand 1 (PDL1), 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 Programmed Cell Death Protein 1 Ligand 1 (PDL1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
