EXPI293F INDUCIBLE CELLS EA，A39241，赛默飞世尔

The Expi293F Inducible cell line is derived from engineered Expi293F cells that stably express the tetracycline repressor (TetR) protein, thus enabling tetracycline-regulated protein expression. The cell line was established by the stable integration of the regulatory plasmid pcDNA6/TR, which encodes the TetR gene under the control of the human CMV promoter. It is a powerful tool for tetracycline-inducible high-yield expression of recombinant proteins.

Features of Expi293 Inducible cells include:
• Suspension, high-density culture in Expi293 Expression Medium
• Tetracycline-inducible protein expression with extremely low basal expression levels
• Equivalent protein yields to parental Expi293F cells—up to 1 g/L
• Significantly higher protein yields than other HEK293 Tet-inducible cell line alternatives

For inducible expression of your protein of interest, pcDNA5/TO mammalian expression vector (Cat. No. V103320) or an equivalent inducible vector is required for tetracycline-regulated gene expression.

Frozen cells are supplied in a vial containing 1 mL of cells at 1 x 10⁷ viable cells/mL in Expi293 Expression Medium and 10% DMSO. The cells should be thawed directly into Expi293 Expression Medium.
