Expi293F™ GnTI- Cells, China

The Expi293F GnTI- cell line is derived from engineered Expi293F cells that do not have N-acetylglucosaminyltransferase I (GnTI) activity and therefore lack complex N-glycans. It is a powerful tool for the high-yield expression of homogeneously glycosylated recombinant proteins.

Features of Expi293F GnTI- cells include:
• Suspension, high-density culture in Expi293 Expression Medium
• Homogeneous N-glycosylation of expressed proteins
• Equivalent protein yields to parental Expi293F cells—up to 1 g/L
• Significantly higher protein yields than other HEK293 GnTI- cell line alternatives

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.
