Abstract
Ascitic fluid (also called ascites) is an intraperitoneal fluid extracted from mice that have developed a peritoneal tumor. For antibody production, the tumor is induced by injecting hybridoma cells into the peritoneum, which serves as a growth chamber for the cells. The hybridoma cells grow to high densities and continue to secrete the antibody of interest, thus creating a high-titered solution of antibodies for collection. A single mouse may yield as much as 10 mL of ascitic fluid or as little as 1 mL per batch. Antibody concentrations will typically be between 1 and 10 mg/mL. The most common problem encountered in storing ascites is contamination of these solutions with bacteria or fungi. This can be prevented by the addition of sodium azide.Keywords
