Evaluation of ethylene-vinyl acetate copolymer as a non-inflammatory alternative to Freund's complete adjuvant in rabbits.
Ethylene-vinyl acetate copolymer (EVAc) was evaluated as an antigen delivery device in laboratory rabbits. Bovine serum albumin (BSA) was incorporated with EVAc in a pellet, which was implanted subcutaneously. Serum antibody titers to BSA in four implanted rabbits were equal to titers in four rabbits injected twice with BSA in complete Freund's adjuvant. Three of four rabbits implanted with EVAc displayed no inflammation or systemic illness in response to the pellet. The fourth rabbit repeatedly developed a small abscess at the implantation site, but the lesions were less severe than complete Freund's adjuvant injection sites. The EVAc pellet is recommended as a non-inflammatory alternative method to Freund's adjuvants for producing serum antibody in rabbits.
