General description

Programmed cell death 1 ligand 2 (UniProt Q9BQ51; also known as B7-DC, B7 dendritic cell molecule, B7-H2, Butyrophilin B7-DC, CD273, PD-1 ligand 2, PD-L2, PDCD1 ligand 2, Programmed death ligand 2) is encoded by the PDCD1LG2 (also known as B7DC, CD273, PDCD1L2, PDL2) gene (Gene ID 80380) in human. PD-1 and PD-1 ligands 1&2 (PD-L1 and PD-L2) are B7:CD28 family members that regulate T cell activation and peripheral tolerance. When engaged together with the TCR, the interaction of PD-1 with its ligands delivers an inhibitory signal to T cell proliferation and cytokine production. While PD-L1 is broadly expressed in hematopoietic and nonhematopoietic cells, PD-L2 expression is highly restricted to antigen presenting cells (APCs), including dendritic cells (DCs) and macrophages. The PD-1 pathway plays a key role in the progressive loss of effector T cell responses during chronic HIV infection. Under some conditions, blockade of this pathway is able to restore many T cell functions. PD-L2 is initially produced with signal peptide (a.a. 1-19) sequence, the removal of which yields the mature protein with a large extracellular (a.a. 20-220) region that contains an Ig-like V-type domain (a.a. 21-118) and an Ig-like C2-type domain (a.a. 122-203), followed by a transmembrane domain (a.a. 221-241) and a cytoplasmic tail (a.a. 242-273).

Quality

Evaluated by Western Blotting in human thymus tissue lysate.

Western Blotting Analysis: 0.5 µg/mL of this antibody detected PD-L2 in 10 µg of human thymus tissue lysate.

Specificity

Clone 24F.10C12 immunostained the surface of 300.19 murine pre-B lymphoma cells transfected with human PD-L2, but not the untransfected cells or cells transfected with human PD-L1 (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266). Reactivity toward spliced isoform 2 (PD-L2II) and isoform 3 (PD-L2III) has not been determined.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
