Monoclonal Antibody Facility
The Facility provides assistance to researchers wishing to generate monoclonal antibodies (mAbs), ascites fluid and other related services.
In addition, the Facility uses adult tolerization or Cyclophosphamide immunosuppression approaches to enhance the probability of producing mAbs against particular antigens in a complex mixture or against a specific part of a molecule.
The Facility has also developed a method to produce high titer polyclonal ascites by immunizing mice with the antigen of interest and then inducing the mice with sarcoma cells. This method can provide 10-18ml polyclonal ascites fluid per mouse using only small aount of antigens.
