| 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. |
| Source
|
Recombinant Human PD-1/PDCD1 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Leu25-Gln167. |
| Molecular Weight
|
The protein has a predicted MW of 17 kDa. Due to glycosylation, the protein migrates to 38-50 kDa based on Tris-Bis PAGE result. |
| Endotoxin
|
Less than 1 EU per μg by the LAL method. |
| Purity
|
>95% as determined by Tris-Bis PAGE.
>95% as determined by HPLC. |
| Formulation
|
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
| Reconstitution
|
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage
|
-20 to -80℃ for 12 months as supplied from the date of receipt.
-20 to -80℃ for 3-6 months in an unopened state after reconstitution.
2-8℃ for 2-7 days after reconstitution. |
| Notes
|
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. |
