Signosis' EL-002 EGFR WT Ba/F3 cell line is a stable cell line generated using the MigR1 vector with an MSCV-IRES-EGFP retroviral construct. EGFR expression is driven by the MSCV promoter, and GFP fluorescence enables efficient selection by FACS. Stable clones were validated for EGFR authenticity and protein expression through PCR sequencing and Western blot analysis.
