Monoclonal Antibodies

Monoclonal antibodies are produced in laboratories to enhance, restore or mimic the immune system's attack on cancer cells. They are made by cloning a specific white blood cell, so every monoclonal antibody can be traced back to a single parent cell.

Product overview

What are monoclonal antibodies?

St John's Laboratory lists tens of thousands of monoclonal antibodies, all traceable to a single parent cell line.

  • A single, consistent epitope Because every monoclonal antibody descends from one parent cell, it binds the same epitope every time, giving consistent results across repeat experiments.
  • Can be designed for monovalent affinity Monoclonal antibodies can also be engineered to have monovalent affinity for their target.
  • A wide range of host species St John's Laboratory offers 39,843 monoclonal antibodies across a range of host species, including mouse, rabbit, and cell-line-derived hosts such as 293F and CHO cells.
Production process

How monoclonal antibodies are made

When an antigen is introduced to either a mouse or a rabbit and polyclonal B cells are fused from the spleen to the myeloma, a hybridoma is created. That hybridoma is then cultured to continue antibody production.
