Stimulation of the TCR results in activation of downstream NFAT signaling. NFAT (Nuclear factor of activated T-cells) is a family of transcription factors that has an important function in immune responses, for example by inducing the expression of various cytokines (such as interleukin-2 to 4, and TNF-alpha) in T cells. NFAT is regulated by Ca\u003csup\u003e2+\u003c\/sup\u003e and the Ca\u003csup\u003e2+\u003c\/sup\u003e\/calmodulin-dependent serine phosphatase, calcineurin. Beta-2-Microglobulin is a required component of MHC class 1 molecules, which present peptide fragments from within the cell to cytotoxic T cells as part of the adaptive immune system. The protein forms amyloid fibrils in some pathological conditions. B2M plays an essential role both in governing MHC class I molecule stability and in promoting antigen binding and presenting the antigen to CD3\/TCR complex of CD8+ T cells. The knockout of both TCR and B2M will support the manufacture of universal CAR-T cells. The ablation of B2M or TCR prevents the elimination of allogeneic T cells that express foreign HLA-I molecules, and thereby enables the generation of CAR-T cells from allogeneic healthy donors T cells with higher persistence in vivo.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eImmunotherapy\u003c\/span\u003e\n\u003cp\u003eThis cell line is a double knockout of TCR (T Cell Receptor) and B2M (Beta-2-Microglobulin). First, the TRAC (T-Cell Receptor Alpha Constant) and the TRBC1 (T-Cell Receptor Beta Constant 1) domains of the TCRα\/β chains were genetically removed by CRISPR\/Cas9 genome editing from NFAT Luciferase Reporter Jurkat cells to generate the TCR Knockout NFAT Luciferase Reporter Jurkat cell Line (BPS Bioscience #78556). These TCR knockout cells were used to generate a new cell line in which B2M was also genetically removed by CRISPR\/Cas9 genome editing. Expression of the firefly luciferase gene is driven by NFAT response elements located upstream of the minimal TATA promoter. Activation of the NFAT signaling pathway in these cells can be monitored by measuring luciferase activity.\u003c\/p\u003e\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Cell Line\u003c\/th\u003e\n\u003ctd\u003eJurkat (clone E6-1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Species\u003c\/th\u003e\n\u003ctd\u003eHuman t lymphoblast, suspension\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTransfection Method\u003c\/th\u003e\n\u003ctd\u003eLentivirus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied As\u003c\/th\u003e\n\u003ctd\u003eEach vial contains 2 x 10\u003csup\u003e6\u003c\/sup\u003e cells in 1 ml of cell freezing medium (BPS Bioscience #79796)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHarmonized Tariff Code\u003c\/th\u003e\n\u003ctd\u003e3002-5900\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eQuality Control \u0026amp; Validation\u003c\/h2\u003e\n\u003cspan class=\"bhp-qc-badge\"\u003e✓ Mycoplasma-Tested\u003c\/span\u003e\n\u003cp\u003eThe cell line has been screened to confirm the absence of Mycoplasma species.\u003c\/p\u003e\n\u003ch2\u003eSafety \u0026amp; Handling\u003c\/h2\u003e\n\u003cdiv class=\"bhp-warning-box\"\u003e\n\u003cp style=\"margin:0 0 4px\"\u003e⚠ Avoid freeze\/thaw cycles.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eRegulatory Information\u003c\/h2\u003e\n\u003cdiv class=\"bhp-regulatory-row\"\u003e\n\u003cdiv class=\"bhp-reg-item\"\u003e\n\u003cstrong\u003eLicense Required\u003c\/strong\u003eYes\u003c\/div\u003e\n\u003cdiv class=\"bhp-reg-item\"\u003e\n\u003cstrong\u003eLiving Modified Organism\u003c\/strong\u003eYes\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eLicense Disclosure\u003c\/h2\u003e\n\u003cdiv class=\"bhp-license-box\"\u003eThe CRISPR\/CAS9 technology is covered under numerous patents, including U.S. Patent Nos. 8,697,359 and 8,771,945, as well as corresponding foreign patents applications, and patent rights.
