Molecular Weight	The secreted recombinant mouse PDCD1 consists of 154 amino acids and has a predicted molecular mass of 17.6 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm PDCD1 is approximately 40-45 kDa due to glycosylation.
predicted N	Leu 25
SDS-PAGE
Purity	> 95 % as determined by SDS-PAGE
Protein Construction	A DNA sequence encoding the extracellular domain (Met 1-Gln 167) of mouse PDCD1 (NP_032824.1) precursor was expressed with a polyhistidine tag at the C-terminus.
Bio-activity	Measured by its binding ability in a functional ELISA. Immobilized mouse PDCD1-His at 10 μg/ml (100 μl/well) can bind mouse CD274-Fch(Cat：50010-M03H), The EC50 of mouse CD274-Fch(Cat：50010-M03H) is 1.0-2.3μg/ml.
Research Area	Signaling |Signal Transduction |ITIM/ITAM Immunoreceptors and Related Molecules
Formulation	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.
Background	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-10 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.
