| Tissue Specificity |
Using a conjugate L.Tyrosine-BSA, antibody specificity was performed with an ELISA test by competition experiments with the following compounds: Compounds Cross-reactivity ratio * L.Tyrosine-G-BSA 1 L.Phenylalanine-G-BSA 1/6,000 L.Tryptophan-G-BSA 1/35,000 L.Tyrosine-GA-BSA 1/>50,000 L.Tyrosine (free) 1/>50,00 *L.Tyrosine-G-BSA concentration / unconjugated or conjugated catecholamine concentration at half displacement. G: Glutaraldehyde, GA: Glutaric anhydride. |
