Description	This 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 TCRalpha/beta chains were genetically removed by CRISPR/Cas9 genome editing from Jurkat cells to generate the TCR Knockout Jurkat cell Line (Biohippo #78539). These TCR knockout cells were then used to generate a new cell line in which B2M was also genetically removed by CRISPR/Cas9 genome editing. Mycoplasma testing: The cell line has been screened to confirm the absence of Mycoplasma species. Host Species: human Supplied as Each vial contains 2 x 10⁶ cells in 1 ml of cell freezing medium (Biohippo #79796)
Background	The T Cell Receptor (TCR) is found on the surface of T-cells and is responsible for recognizing antigens bound to MHC (Major Histocompatibility Complex) molecules. Stimulation of the TCR triggers a signaling cascade that leads to the activation of transcription factors involved in the upregulation and secretion of cytokines, T cell proliferation, and cell differentiation into effector and memory cells. TCR-activated transcription factors include AP-1 (Activator Protein 1), NF-kappaB (Nuclear Factor Kappa-light-chain-enhancer of activated B cells) and NFAT (Nuclear Factor of Activated T-cells).Beta-2-Microglobulin is a required component of Major Histocompatibility Complex (MHC) class 1 molecules, which present peptide fragments from within the cell to cytotoxic T cells as part of the adaptive immune system. B2M plays an essential role both in governing MHC class I molecule stability and in promoting antigen binding by presenting the antigen to CD3/TCR complex of CD8+ T cells.Knockout of both TCR and B2M will support the manufacture of universal CAR-T cells. Knockout of TCR or B2M prevents the elimination of allogeneic T cells that express foreign HLA-I molecules, thereby enabling the generation of CAR-T cells from allogeneic healthy donors T cells in vivo.
Application	Useful for the development of improved universal CAR-T or other effector cells.
