Use at an assay dependent concentration. Can be paired for Sandwich ELISA with Rabbit monoclonal [PSH09-80] to Human PD-L2 antibody (Capture) (HA723145) or Rabbit monoclonal [PSH09-81] to Human PD-L2 antibody (Capture) (HA723146) and Recombinant Human PD-L2 protein (HA210599) as the standard.
Target
Function
Involved in negative regulation of activated T cell proliferation; negative regulation of interferon-gamma production; and negative regulation of interleukin-10 production. Predicted to be located in plasma membrane. Predicted to be active in external side of plasma membrane. Biomarker of pulmonary tuberculosis. 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.

Sandwich ELISA analysis of Human PD-L2 matched pair antibodies
Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA723146) diluted in carbonate/bicarbonate buffer, at a concentration of 0.5ug/ml overnight at 4℃. Wells of the plate were washed, blocked with 150 µl 0.05% tween-20 1% BSA blocking buffer, and incubated with serial diluted Recombinant Human PD-L2 (HA210599) starting from 111.11 ng/ml to 0 ng/ml and detect antibody (HA723373H, HRP, 0.01 µg/ml) for 1 hour at 30℃ with shaking. Detection was performed using an Ultra TMB Substrate for 10 minutes at room temperature in the dark. The reaction was stopped with sulfuric acid and absorbances were read on a spectrophotometer at 450 nm.
