Monoclonal
antibody services
ProSci's Custom Monoclonal Antibody Team are experts in the development and production of antibodies utilizing hybridoma technologies. We have specially-developed techniques to ensure successful hybridoma development with a fusion success rate of over 98%. We guarantee stable cell lines with ELISA-positive clones and careful screening throughout monoclonal antibody development.
Our step-by-step process starts with antigen design and goes through Immunization, ELISA testing of serum, fusion, subcloning, and isotyping of final clones. ProSci's custom process allows flexibility along each step of development allowing for custom options that can be implemented based on our clients' needs.
