The concentration of histamine in sera of histamine receptor knockout mice.
An ELISA (R&D Systems and Immunotech, Marseille, France) showed that histamine receptor knockout mice (H2R-KO) mice (n = 8) had higher serum levels of histamine than WT (n = 8), and H1R-KO mice (n = 8) that were maintained for 11 weeks on a normal chow diet. Values represent the mean ± SD of triplicate measurements from three independent experiments (*P < 0.05, N.S: not significant).
