Trichoplusia ni Cell Line (Tni-FNL)

Trichoplusia ni cell line derived from BTI-Tn-5B1-4, adapted for suspension growth and serum-free growth.


  • Used for protein expression by baculovirus infection
  • Can grow efficiently at 21 or 27 C in adherent or suspension conditions

The baculovirus expression vector system (BEVS) has proven to be a powerful technology for expression of recombinant proteins in eukaryotic cells. The BEVS technology has many advantages that include the capacity for large DNA insertions, the capacity for simultaneous expression of multiple genes, high expression levels for many proteins, and posttranslational modifications that often resemble those found in mammalian cells.
