Signosis' EL-002 EGFR WT Ba/F3 cell line is a stable cell line generated by lentiviral transduction using MSCV-IRES-EGFP expression cassette. EGFR expression is driven by the MSCV promoter, while GFP fluorescence enables efficient selection of transduced cells by fluorescence-activated cell sorting (FACS). Stable clones were validated for EGFR sequence authenticity and protein expression by PCR sequencing and Western blot analysis.
