This cell line is a knockout of TCR (T Cell Receptor). The TRAC (T-Cell Receptor Alpha Constant) and TRBC1 (T-Cell Receptor Beta Constant 1) domains of the TCRα/β chains were genetically removed by CRISPR/Cas9 genome editing from recombinant Jurkat cells stably expressing the firefly luciferase gene under the control of NFAT response elements.This cell line has been functionally validated and does not respond to anti-CD3 agonist antibodies, as opposed to parental NFAT-Luciferase Reporter Jurkat cells (BPS Bioscience #60621).
