Our Recombinant Platform
Proteintech’s custom antibody service utilizes its proprietary ABCE™ (Antigen-Specific B-Cell Cloning & Engineering) platform, which provides the following advantages:
- High-yield expression: Enables stable and efficient production of recombinant monoclonal antibodies.
- Preserves native VH-VL pairings: Maintains natural antibody specificity and functionality, unlike phage display
- Efficient and fast: Produces more positive clones from fewer cells in less time compared to traditional hybridoma methods.
- High-throughput capability: Supports rapid development of Uni-rAb™ off-the-shelf antibodies.
- Precise Antigen Design: Our scientists bring decades of experience in generating antigens tailored to your specific needs, including challenging targets and post-translational modifications.
