Custom Recombinant Services
Antibody Development and Production
ProSci's Custom Recombinant Antibody Team are experts in the development and production of antibodies utilizing phage display or B cell cloning.
Our step-by-step process starts with antigen design and goes through immunization, single-cell sorting, culturing, and screening, and completes with cloning, small-scale expression, and delivery of a research-ready antibody. ProSci's custom process allows flexibility along each step of development allowing for custom options that can be implemented based on our client's needs.
