Human PD-L2 / B7-DC Protein, mouse IgG1 Fc Tag

  • Synonym
    PDL2,PD-L2,Butyrophilin B7-DC,CD273,PDCD1 ligand 2,PDCD1L2,PDCD1LG2
  • Source
    Human PD-L2, mouse IgG1 Fc Tag (PD2-H52A5) is expressed from human 293 cells (HEK293). It contains AA Leu 20 - Pro 219 (Accession # AAI13679).
    Predicted N-terminus: Leu 20
  • Molecular Characterization
    PD-L2(Leu 20 - Pro 219) AAI13679

    This protein carreis a mouse IgG1 Fc tag at the C-terminus, and has a calculated MW of 48.9 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 by the LAL method.
  • Purity

    >95% as determined by reduced SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Human PD-L2, mouse IgG1 Fc Tag (Cat. No. PD2-H52A5) SDS-PAGE gel

Human PD-L2, mouse IgG1 Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

Bioactivity
Human PD-L2, mouse IgG1 Fc TagHuman PD-L2, mouse IgG1 Fc Tag (Cat. No. PD2-H52A5) ELISA bioactivity

Immobilized Human PD-1, His Tag (Cat. No. PD1-H5221) at 2 μg/mL (100 μL/well) can bind Human PD-L2, Mouse IgG1 Fc Tag (Cat. No. PD2-H52A5) with a linear range of 10-156 ng/mL (QC tested).

Human FcRn Heterodimer Protein Cell_Base

Flow Cytometry assay shows that recombinant Human PD-L2, mouse IgG1 Fc Tag (Cat.No. PD2-H52A5) can bind to 293 cell overexpressing human PD-1. The concentration of PD-L2 used is 0.1 ug/ml (Routinely tested).

Human FcRn Heterodimer Protein Cell_Base

FACS analysis shows that the binding of Human PD-L2, mouse IgG1 Fc Tag to 293 overexpressing PD-1 was inhibited by increasing concentration of neutralizing anti-PD-1 antibody. The concentration of PD-L2 used is 0.1 ug/ml. The IC50 is 1.3 μg/mL (Routinely tested).
