背景介绍 TIGIT is a co-inhibitory receptor that is highly expressed in Natural Killer (NK) cells, activated CD4+, CD8+ and regulatory T cells. Interaction with the poliovirus receptor (PVR; CD155) on antigen presenting cells, such as dendritic cells, recruits Src homology (SH) domain-containing protein tyrosine phosphatase SHP1 and SHP2 or the inositol phosphatase SHIP1 and SHIP2 to the TIGIT ITIM domain. This increases IL-10 release and suppresses NF-kB and NFAT T cell receptor (TCR) signaling, which blocks T cell proliferation and cytokine production. It serves as a competitive inhibitor of CD226, a co-stimulatory receptor for CD155. TIGIT targeting antibodies that block this T cell-intrinsic inhibitory effects have shown enhanced anti-tumor and anti-viral functions in preclinical studies. 产品介绍 Recombinant Jurkat cell line constitutively expressing a full length human TIGIT (T cell Immunoreceptor with Immunoglobulin and ITIM domain; VSTM3), and a firefly luciferase gene under the control of nuclear factor of activator T cells (NFAT) response element. Both TIGIT and NFAT constructs have been stably integrated into Jurkat cells. TIGIT expression has been confirmed by Western Blot, and TIGIT-specific NFAT response has been validated using a TIGIT ligand, CD155 (PVR).
询价背景介绍 CD155 is a transmembrane glycoprotein receptor belonging to the immunoglobulin superfamily. It is highly expressed on dendritic cells, fibroblasts, endothelial cells, and multiple tumor cells including ovarian carcinoma, non-small cell lung, glioblastoma, and colorectal carcinoma. It has a high affinity for a T cell regulatory transmembrane surface protein called TIGIT (T cell immunoglobulin and ITIM domains), and plays a key role in tumor cell invasion and migration. Interaction between CD155 and TIGIT causes immunosuppressive effects on CD4+ and CD8+ T cells, which hinders T cell proliferation and function. CD155 also interacts with regulatory receptors CD226 (expressed on natural killer (NK) cells, monocytes and CD4+ T cells) and CD96. While CD155-CD226 engagement activates NK cell cytotoxicity and T cell response, CD155-CD96 interaction inhibits NK cell function. Due to these opposing regulatory effects, blockade of CD155-TIGIT and CD155- CD226 interactions are attractive therapeutic strategies in cancer immunotherapy and autoimmune diseases, respectively. 产品介绍 Recombinant HEK293 cell line expressing full length human CD155, also known as poliovirus receptor (PVR) or nectin-like molecule-5 (NECL-5). Expression is confirmed by Western Blot.
询价背景介绍 The binding of Programmed Cell Death Protein 1 (PD-1), a receptor expressed on activated Tcells, to its ligands, PD-L1 and PD-L2, negatively regulates immune responses. The PD-1 ligands are found on most cancers, and PD-1:PD-L1/2 interaction inhibits T cell activity and allows cancer cells to escape immune surveillance. The PD-1:PD-L1/2 pathway is also involved in regulating autoimmune responses, making these proteins promising therapeutic targets for a number of cancers, as well as multiple sclerosis, arthritis, lupus, and type I diabetes. 产品介绍 Recombinant CHO-K1 cells constitutively expressing human PD-L1 (Programmed Cell Death 1 Ligand 1, CD274, B7 homolog 1 (B7- H1), GenBank accession # NM_014143) an engineered T cell receptor (TCR) activator.

询价背景介绍 L-tryptophan (L-Trp) is an essential amino acid necessary for protein synthesis in mammalian cells and the L-Trp to kynurenine (Kyn) pathway is firmly established as a key regulator of innate and adaptive immunity. Catabolism of L-Trp to Kyn maintains an immunosuppressive microenvironment by starving immune cells of L-Trp and releasing degradation products of L-Trp that have immunosuppressive functions. Tryptophan 2,3 dioxygenase (TDO), is upregulated in many tumors, providing cancer cells with an avenue for immune evasion. 产品介绍 Stable recombinant HEK293 cell line expressing human tryptophan 2,3 dioxygenase (TDO2, TDO, TPH2, TRPO), Genbank accession number NM_005651.

询价背景介绍 Nav1.8 is a voltage gated type X, alpha subunit sodium channel which in humans is encoded by the SCN10A gene. It is expressed in nociceptors and has been proposed as a target for the development of new analgesics. Mice deficient in Nav1.8 have deficits in sensing inflammatory pain (initiated by tissue damage/inflammation) and visceral pain (initiated by damage or injury to internal organs) but not neuropathic pain. Native sodium channels are complexes composed of the pore-forming α subunit and an auxiliary β subunit. The sodium channel β2 subunit, encoded by the SCN2B gene, increases current amplitude and surface expression of sodium ion channels. 产品介绍 Stable recombinant HEK293 cell line expressing tetracycline-inducible human Nav1.8 (Genbank #NP_006505.2) fused to Green Fluorescent Protein (GFP) [Ex. ~395 nm, 475 nm; em ~510 nm] and C-terminal Streptavidin-Binding Peptide (SBP)-tag, and the human sodium channel β2 subunit (Genbank #NM_004588; SCN2B) with C-terminal FLAG-tag. Nav1.8 is also known as tetrodotoxin-resistant voltage-gated sodium channel type X (SCN10A).
