Antibody Expression and Purification


The titer and yield of recombinant antibody production has dramatically increased in the last couple decades, which is directly correlated to the extensive research driven by the demand of therapeutic antibodies. With a package of licensed cell line and expression vectors and a unique and extremely efficient transfection reagent, we can continue to push the obtained results to a new level.

Cell Line: HEK293, CHO. (in serum-free, suspension culture)

Expression method: Transient, with special transfection reagent.

Yield: up to 500 mg/liter.

Saving animals: If you have a hybridoma cell, we can retrieve the antibody gene and produce the antibody in mammalian cells. This allows you to get to know your antibody, while it's preserved as stable DNA or digital sequence data.
