Bovine chymotrypsin enhances the production of IgE and IgG1 by murine spleen cells stimulated with LPS plus IL-4. Spleen cells from BALB/c mice were cultured with or without indicated concentration of bovine chymotrypsin (open squares) or DFP-treated chymotrypsin (closed squares) in the presence of LPS plus IL-4 for 7 days. IgE (a) and IgG1 (b) in the supernatant were quantitated by ELISA. Each symbol and bar represent mean and standard error of mean (SEM; n = 6). Values obtained from the culture containing chymotrypsin were compared with values from the culture without chymotrypsin by Dunnett's method (*, P < 0·05; **, P < 0·01).
