Involved in the costimulatory signal, essential for T-cell proliferation and IFNG production in a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation by blocking cell cycle progression and cytokine production (By similarity).

NP_079515

This assay has high sensitivity and excellent specificity for detection of Programmed Cell Death Protein 1 Ligand 2 (PDCD1LG2).No significant cross-reactivity or interference between Programmed Cell Death Protein 1 Ligand 2 (PDCD1LG2) and analogues was observed.

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 2 (PDL2). 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 2 (PDL2). 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 2 (PDL2), 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 2 (PDL2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Programmed Cell Death Protein 1 Ligand 2 (PDL2) 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 2 (PDL2) were tested on 3 different plates, 8 replicates in each plate.
