We provide a fast and reliable scale-up monoclonal antibody from transient production. Utilizing a dual high-copy vector system, F(ab)2 and Fc fragments are co-transfected into a mammalian cell line. These transfected cells are then amplified in optimized serum-free, suspension culture, and the expressed antibodies are purified with affinity chromatography. Final products are quality-tested with IgG antibody SDS-PAGE Coomassie Blue staining and ELISA. Transient antibody production can produce the desired quantity of up to 100mg within 2-3 weeks.
