生物活性
Measured by its binding ability in a functional ELISA . Immobilized recombinant mouse PD1-L1 at 1 μg/ml (100 μl/well) can bind mouse PD1 with a linear range of 6.25-400 ng/ml .
蛋白构建
A DNA sequence encoding the extracellular domain (Met 1-Gln 167) of mouse PDCD1 (NP_032824.1) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

分子量
The recombinant mouse PDCD1/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 391 amino acids and has a predicted molecular mass of 44.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm PDCD1/Fc monomer is approximately 60-65 kDa due to glycosylation.
缓冲液
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

PD-1 背景信息

Programmed cell death 1, also known as PDCD1, is a type I transmembrane glycoprotein, and is an immunoreceptor belonging to the CD28/CTLA-4 family negatively regulates antigen receptor signaling by recruiting protein tyrosine phosphatase, SHP-2 upon interacting with either of two ligands, PD-L1 or PD-L2. PD1 inhibits the T-cell proliferation and production of related cytokines including IL-1, IL-4, IL-1 and IFN-γ by suppressing the activation and transduction of PI3K/AKT pathway. In addition, coligation of PD1 inhibits BCR-mediating signal by dephosphorylating key signal transducer. PD1 has been suggested to be involved in lymphocyte clonal selection and peripheral tolerance, and thus contributes to the prevention of autoimmune diseases. Furthermore, PD1 is shown to be a regulator of virus-specific CD8+ T cell survival in HIV infection. As a cell surface molecule, PDCD1 regulates the adaptive immune response. Engagement of PD-1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function.
