B7-H7 (B7 homolog 7), also know n as HHLA2 (human endogenous retrovirus-H long terminal repeat-associating protein 2), is regarded as a new member of the B7 ligand family. B7-H7 contains 1 Ig-like (immunoglobulin-like) C1-type and 2 Ig-like V-type domains while other members are typically composed of 1 Ig-like V-type and 1 Ig-like C1-type domains. Interactions between members of the B7 ligand and CD28/CTLA4 receptor families can generate positive co-stimulation and negative co-inhibition in regulating T cell responses. B7-H7 is expressed at high levels in colon, kidney, testis, lung and pancreas, and at lower levels in small intestine, liver and skeletal muscle. In immune cells, B7-H7 is highly expressed in B-cells, dendritic cells, monocytes and macrophages, but not detected in T-cells. B7-H7 was reported to regulate cell-mediated immunity by binding to a putative receptor on T lymphocytes and inhibiting the proliferation of T cells. B7-H7 has also been referred to as B-H5 (B7 homolog 5), which was identified as a specific ligand for CD28H (CD28 homolog) or TMIGD2 (transmembrane and Ig domain-containing protein 2). B7-H5 is constitutively found in macrophages and could be induced on dendritic cells in response to inflammation. The B7-H5/CD28H interaction was shown to selectively co-stimulate human T-cell growth and cytokine production via an AKT-dependent signalling cascade.
Gene Symbol: B7-H7; HHLA2; B7H7; B7-H5; B7H5
NCBI Gene ID: 11148
Uniprot Entry: Q9UM44
Construct Details: Full length human B7-H7/HHLA2 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.
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: 1245 (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.
