>PE-Labeled Human PD-1 / PDCD1 Protein, Fc Tag, His Tag (recommended for neutralizing assay)
This protein carries a human IgG1 Fc tag at the C-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 44.7 kDa.
Excitation source: 488 nm spectral line, argon-ion laser
Excitation Wavelength: 488 nm
Emission Wavelength: 575 nm
Lyophilized from 0.22 μm filtered solution in PBS, 0.5% BSA, pH7.4. Normally trehalose is added as protectant before lyophilization.

Flow Cytometry assay shows that PE-Labeled Human PD-1, Fc Tag, His Tag (recommended for neutralizing assay) (Cat. No. PD1-HP2F2) can bind to 293T cells overexpressing human PD-L1. 1 μl stock solution per million cells (QC tested).
FACS analysis shows that the binding of PE-Labeled Human PD-1, Fc Tag, His Tag (recommended for neutralizing assay) (Cat. No. PD1-HP2F2) to 293T overexpressing PD-L1 was inhibited by increasing concentration of neutralizing anti- human PD-L1 antibody. The IC50 is 0.29 μg/ml (QC tested).
