(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Activity
①M(fèi)easured by its binding ability in a functional ELISA. Immobilized PD-1 at 2 μg/ml can bind Anti-PD-1 recombinant antibody, the EC₅₀ of human PD-1 protein is 6.087-7.854 ng/ml.

Activity
②Measured by its binding ability in a functional ELISA. Immobilized PD-1 at 2 μg/ml can bind Nivolumab, the EC₅₀ of human PD-1 protein is 9.713-12.39 ng/ml.

The purity of PDCD1 was greater than 95% as determined by SEC-HPLC

Western Blot
Positive WB detected in: MCF-7 whole cell lysate
All lanes: PD1 antibody at 1:2000
Secondary
Goat polyclonal to rabbit IgG at 1/50000 dilution
Predicted band size: 32 KDa
Observed band size: 32 kDa

IHC image of CSB-RA240597A0HU diluted at 1:100 and staining in paraffin-embedded human tonsil tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
