Test Principale: This assay employs a two-site sandwich ELISA to quantitate PDCD1LG2 in samples. An antibody specific for PDCD1LG2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPDCD1LG2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PDCD1LG2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PDCD1LG2 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Product Overview: Using flow cytometric analysis, Latchman et al. (2001) showed that the IgV region of mouse Pdl2, like Pdl1, binds to human PDCD1 but not to CTLA4, CD28, or ICOS. Stimulation of mouse T cells with anti-CD3 and Pdl2 or Pdl1 resulted in inhibition of proliferation and cytokine production, and Pdl2 could inhibit T-cell receptor -CD28 signals at low antigen concentrations. Latchman et al. (2001) proposed that blocking of the PDL-PDCD1 pathway may enhance antitumor immunity, whereas stimulating this pathway may help downregulate graft rejection and autoimmune and allergic reactions. Latchman et al. (2001) mapped the PDL2 gene to chromosome 9p24.2, in close proximity to the PDL1 gene. Tseng et al. (2001) mapped the mouse Pdl2 gene to chromosome 19C2-C3.

Stability: The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C) .
