Description

PD-L1 (programmed cell death 1 ligand 1) or CD274 is a 290-amino acid single pass type I transmembrane protein of the Ig (immunoglobulin) superfamily.  It contains one Ig V-like and one Ig C-like domains in the extracellular region, and a 30-amino acid cytoplasmic tail. It was originally cloned as a homolog of B7 (termed B7-H1). It is 20% and 15% identical to B7-1 (CD80) and B7-2 (CD86), respectively.  It was also cloned as a ligand (termed PDCD1L1 or PD-L1) that binds to PD-1 (CD279) and B7-1 (CD80), but not to other B7 family members, such as CTLA4 (CD152), CD28, or ICOS (CD278).  PD-L1 or CD274 is involved in the T cell costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNγ. Interaction with PD-1, which has a cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM), inhibits T-cell proliferation and cytokine production.  PD-L1 is up-regulated on T- and B-cells, dendritic cells, keratinocytes and monocytes after LPS and IFNγ activation or by surface Ig cross-linking. It is expressed in many types of freshly isolated human cancers but not in most normal tissues.  Blockade of PD-L1 upregulates IL12 expression and enhances antitumor immunity in mice bearing ovarian tumors.  Therefore, PD-L1 has been proposed as a target for cancer immunotherapy through pre-activated T cells that could be enhanced by blockade of PD-L1-induced inhibitory signaling. 

 


 

Gene Symbol: PD-L1; CD274; B7-H1; B7H1;  PDL1;  PDCD1L1; PDCD1LG1

 

NCBI Gene ID: 29126

 

Uniprot Entry: Q9NZQ7

 

Construct Details: Full length human PD-L1 or CD274 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Cell surface PD-L1 expression can be monitored by anti-PD-L1 antibody (SKU#: MAB0199).

 

Vector Type: pLTC (lentiviral expression vector containing a heterologous CMV promoter, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 873 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CGGGAAGCAATAGCATGATA-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
