Background
Programmed cell death 1 ligand 2 (PD-L2 or PDCD1 ligand 2) is also known as Butyrophilin B7-DC, CD antigen CD273, which belongs to the immunoglobulin superfamily or BTN/MOG family. The expression of PD-L2 is up-regulated by IFNG/IFN-gamma stimulation in monocytes and induced on dendritic cells grown from peripheral blood mononuclear cells with CSF2 and IL-4. PD-L2 Involved in the costimulatory signal, essential for T-cell proliferation and IFNG production in a PDCD1-independent manner. PD-L2 interaction with PDCD1 inhibits T-cell proliferation by blocking cell cycle progression and cytokine production.

Source
Human PD-L2, Fc Tag (HPLC verified) (PD2-H5251) is expressed from human 293 cells (HEK293). It contains AA Leu 20 - Pro 219 (Accession # AAI13679).
Predicted N-terminus: Leu 20

Molecular Characterization
Human PD-L2, Fc Tag (HPLC-verified) is fused with a human IgG1 Fc tag at the C-terminus, and has a calculated MW of 49.2 kDa. The predicted N-terminus is Leu 20. The reducing (R) protein migrates as 60-70 kDa in SDS-PAGE due to glycosylation.

Endotoxin
Less than 1.0 EU per μg of the Human PD-L2, Fc Tag (HPLC-verified) by the LAL method.

Purity
>95% as determined by SDS-PAGE.
>90% as determined by SEC-HPLC.

Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
