HUGO-Ab™: Next-Generation Fully Humanized Antibody Mouse Models

Cyagen Biosciences has exclusively developed HUGO-Ab™ fully humanized antibody mice that can produce fully humanized antibodies with high affinity and low immunogenicity in vivo. Its outstanding performance potential has been demonstrated by excellent results in the preclinical antibody discovery process, gaining recognition from multiple multinational pharmaceutical companies, biotech companies, and academic institutions.  HUGO-Ab™ mice are poised to serve as an efficient research and development model for new therapeutic antibody drugs.

Single B Cell Screening Antibody Discovery & Development Platform

Biointron's independently developed single B cell antibody development platform relies on microdroplet microfluidic systems and efficient signal amplification technology to achieve high-throughput identification of plasma cells secreting specific antibodies, capable of screening up to 2 x 106 plasma B cells from immunized animals within one day. The large number of positive cells obtained through screening are then processed by Biointron's single-cell sequencing platform, achieving the acquisition of naturally paired antibody sequences within a week. Furthermore, antigen specific antibody-secreting cells can be isolated, allowing for the detection of potentially rare antibodies and drugs. This strategic cooperation will comprehensively accelerate the innovative pace of fully humanized antibody drug research and development.
