特異性：Using a conjugate Histamine-PC, antibody specificity was performed with an ELISA test by competition experiments with the following compounds: Compounds = Cross-reactivity ratio (a) Histamine-PC = 1 1-Methyl-Histamine-PC = 1 Histidine-PC = 1/>50,000 (a): Histamine-PC concentration/other conjugated amino acids concentration at half displacement IC50 = 1 X 10 -9 M
純度：The ascitic fluid was purified by ammonium sulfate precipitation
