Dinitrophenyl (DNP) is not found endogenously in tissues and is an excellent alternative to biotin for use in applications requiring biotin-free systems. DNP is smaller than other non-biotin alternatives and thus may allow better penetration of the probe in tissue applications. Probes or antibodies labeled with DNP can be detected using alkaline phosphatase labeled anti-DNP, using biotinylated anti-DNP followed by a streptavidin or avidin system, or using unconjugated anti-DNP followed by a secondary antibody detection system.
These reagents can be used to detect FastTag®-, 3’ or 5’ EndTag™-labeled probes in applications such as in situ hybridization or Southern and northern blotting. All antibodies have been affinity-purified. |
