Preparation of Specific Complement-Fixing Antigens from the Three Prototypes of Poliomyelitis Viruses.

Abstract
Specific complement-fixing antigens were prepared from Lansing-, Brunhilde-, and Leon-infected tissues by sedimentation of the viruses in the high speed centrifuge and using the resuspended sediment as antigen. In the preparation of complement-fixing antisera in monkeys it was advantageous to mix the virus inoculum with an oily, depot-producing adjuvant.
