>Human PD-L2 / B7-DC Protein, Mouse Fc Tag
This protein carries a mouse IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 48.9 kDa. The protein migrates as 60-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by reduced SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

No activity loss was observed after storage at:
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%.
Flow Cytometry assay shows that 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 μg/mL (Routinely tested).
FACS analysis shows that the binding of Human PD-L2, Mouse IgG1 Fc Tag (Cat. No. PD2-H52A5) 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 μg/mL. The IC50 is 1.3 μg/mL (Routinely tested).
