| Protein Construction |
PD-1/PDCD1 (Leu25-Val170)
Accession # NP_001301026.1 |
hFc |
| N-term |
C-term |
|
| Purity |
> 95% as determined by BisTris PAGE
> 95% as determined by HPLC |
| Endotoxin Level |
Less than 1EU per μg by the LAL method. |
| Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized PD-1/PDCD1 hFc Chimera, Canine at 2μg/ml (100μl/well) on the plate can bind Human PDL1, mFc Tag. Test result was comparable to standard batch. |
| Expression System |
HEK293 |
| Theoretical Molecular Weight |
43.00 kDa |
| Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 55-70 kDa based on Bis-Tris PAGE result. |
| Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). |
| Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background |
Programmed cell death protein 1, also known as PD-1 and CD279 , is a protein found on the surface of cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self tolerance by suppressing T cell inflammatory activity. |
| Synonyms |
PDCD1; PD1; CD279; SLEB2; PD-1 |
