Rx Biosciences offers custom phage display library construction for antibody screening and development. We build high-quality scFv and Fab libraries from species including mouse, human, rabbit, chicken, and llama.
Each phage display library is developed using a phagemid vector, with either variable light (vL) or heavy (vH) chains cloned separately, or both together, connected by a linker. These libraries are ideal for discovering and producing monoclonal antibodies.
Whether for research or therapeutic use, our custom phage display libraries provide the flexibility and specificity needed for reliable antibody screening.
Service Highlights
