Monoclonal antibody production

It is hard to imagine a world without monoclonal antibodies (mAbs), as reagents and therapeutics in their own right; they have played an important role in the advancement of basic research, diagnostics and product development.

The production of custom antigen specific mouse monoclonal antibody is a time consuming and technically demanding process. The production of antibodies is conducted at our state-of-the-art facilities either in the US or UK, utilizing Envigo purpose bred models. Our highly-trained personnel provide you with unparalleled expertise across a wide range of antibody services.

In vitro monoclonal antibody production

Envigo Bioproducts has the expertise to produce your monoclonal or secreted protein in vitro. We have the capacity to produce 10mg-300g of research or cGMP antibody, or other secreted proteins, in our innovative tissue culture bag and hollow fiber production units. We offer a variety of media options such as RPMI, DMEM, IMDM, serum free, protein free, or other custom media formulations.

Hybridoma development

Envigo scientists, veterinarians and technicians have more than 40 years of experience refining our approach to developing monoclonal antibodies from a wide variety of peptides and proteins. While our procedures are well-defined, we are flexible when we need to be.

Envigo Bioproducts' hybridoma development program is a flexible, interactive, and cost effective multi-phased service. We will work closely with you to design a program that will meet your requirements. Our custom development options include providing up to three, five, or ten clones, or as many as you require. As our client, you retain all rights to any clones that are produced. Once the clones are developed, we can scale them up as tissue culture supernatant.

ServiceRequirementsProject outcomes

Stage I: Immunization

Immunize mice with antigen
Boost/test by ELISA or alternate method
Additional boost(s) if needed
Pre-fusion boost

Move mice with best titers as fusion candidates
Immunizing multiple mice increases success

Stage II: Fusion/screen and select

Fusion with myeloma cell line
Grow cells in HAT medium
Initial screen/selection
Screen

Screen all initial plates
Expand positive wells and test by ELISA
Set up to 30 positives for cloning
Keep frozen back–up for future testing

Stage III: Cloning/frozen stock

First cloning
Final cloning
Selection for non-HT requirement
Frozen stock and small antibody scale-up

Clone by limiting dilution method
Test clones by ELISA
Several cloning cycles
Final clones expanded and small amount of antibody produced
