To meet the growing demand for rapid, high-throughput screening of antibody candidates during antibody drug development, Quintara has launched the HTP Recombinant Antibody Service. Our high-throughput platform can deliver a range of purified antibody products—including IgGs, Fab, scFv, VHH, di-scFv from micrograms to milligrams. This service enables fast and small-scale antibody expression, with production in as fast as 2 weeks.
Powered by our self-developed high-throughput recombinant antibody expression platform, the system supports a capacity of up to 1,000 projects per month. The service is based on a mammalian cell expression system and utilizes our proprietary high-expression vector, which is transfected into CHO or HEK293 cells for efficient recombinant antibody production.
Final delivery includes recombinant antibodies with >95% purity, and customizable specifications for HPLC purity, endotoxin levels, and concentration—tailored to suit your downstream application needs.
Wide Range of Types
IgGs, scFv, Fab, VHH, di-scFv and more
Fast Turnaround
2 weeks, from gene to antibody
Tailored in Quantity
From mL to L From μg to mg
Large Capacity
1,000 antibody expression per month
