General description

CHOZN cell lines were created utilizing Sigma′s proprietary CompoZr Zinc Finger Nuclease (ZFN) technology to create genetic modifications in parental CHO-K1 cells. Cells are banked in chemically defined, animal component free EX-CELL CD CHO Fusion media

Cell Line Origin

CHOZN cell lines are all subclones of the parental CHO-K1 cell line originated by Puck in 1957.

Physical form

CHOZN cell lines are provided to customers in vials containing >7.5e6 cells/mL

Legal Information

All CHOZN cell lines are sold under license from Sigma Aldrich. A copy of the research license is provided with purchase of the CHOZN cell lines.
