DNP-X, SE, 6-(2,4-Dinitrophenyl)aminohexanoic Acid, Succinimidyl Ester

The amine-reactive DNP-X succinimidyl ester can be used bioconjugates that can be detected with anti-dinitrophenyl (anti-DNP) antibodies. This reactive hapten contains an additional seven-atom aminohexanoyl spacer ('X') between the fluorophore and the succinimidyl ester group. This spacer helps to separate increase accessibility to anti-DNP antibodies.
