The 5A's of Antibody Development Guide


At ProSci, our customer’s success is important to us. We want your project to be successful, and for us to help you we need to know exactly what kind of antibody you need. We created the Antibody Learning Center in order to give you the tools to understand what kind of antibodies there are and how we can tailor them to your individual needs. Inside you will find information about how our custom antibody services work, the challenges we face, and how we resolve them. Please look around, and if you can’t find an answer to your question, send an email to for a personal response.

The nature of the antigen is an important consideration when choosing a method of antibody develpoment. Characteristics such as size and immunogenicity are important components.


The magnitude of the immune response is a crucial factor in antibody generation and production. Adjuvants serve as an immunostimulatory agent during immunization.


The antibody response to a give antigen varies between species; each species is characterized by advantages and limitations.
