Scientific Background
Enhanced green fluorescent protein (eGFP) is a widely used fluorescent reporter derived from Aequorea victoria GFP, engineered for brighter fluorescence and improved folding in mammalian cells. eGFP emits green fluorescence (excitation 488 nm, emission 507 nm) and serves as a versatile tool for cell tracking, gene expression monitoring, and protein localization studies.
Product Description
Stable Cell LineHEK293T-eGFP is a stable cell line generated by transducing HEK293T cells with the LV-EF1a-eGFP-IRES-Puro lentiviral vector (SKU: BHV22000006), followed by puromycin selection. The constitutive EF1a promoter drives robust eGFP expression, making this cell line ideal for fluorescence imaging, assay development, and experimental optimization. The puromycin-resistance cassette enables antibiotic selection and maintenance of a consistently eGFP-positive cell population. Each cryopreserved vial contains approximately 3 × 10⁶ cells.

QC & Validation
Experimentally Validated
Each lot undergoes quality control testing to confirm stable transgene expression. Cells are validated through a minimum of 30 serial passages to ensure long-term expression stability, and cryopreserved stocks are tested for viability retention up to 5 years at −80°C. Mycoplasma screening is performed on every lot to confirm negative status.
Usage Notes
Thaw the cryopreserved vial rapidly in a 37°C water bath until a small ice crystal remains. Transfer cells to a pre-warmed culture vessel containing complete growth medium (DMEM supplemented with 10% FBS and appropriate antibiotics). Allow cells to attach for 12–24 hours before changing medium. Maintain selection pressure with puromycin at the recommended concentration (1.0 µg/mL) to preserve transgene expression.
Culture at 37°C in a humidified atmosphere with 5% CO₂. Passage cells at 70–90% confluency using standard trypsinization protocols. Do not exceed passage 20 for optimal transgene expression stability.
