Cytokine production in the peritoneal lavage of TG5 and FVB mice after thioglycolate injection.

Time course of immunoreactive IL-9 (A), IL-5 (B), and IL-4 (C) protein release in the peritoneal lavage was analyzed using ELISA. Supernate samples were harvested before and 1, 6, 12, 24, 48, and 72 hours after thioglycolate injection, respectively. Open circles indicate cell numbers in FVB mice; solid circles, cell numbers in TG5 mice. Values are expressed in pg/mL as mean ± SEM (n = 4 for each time point and each genotype).
