NBD-X SE

Orange powder. Soluble in DMSO or DMF. Chemical. CAS: 145195-58-0. Formula: C16H17N5O7. MW: 391.33. Synthetic. NBD-X, SE is an excellent amino-reactive building block that can be used to prepare peptide conjugates and other bioconjugates/biopolymers. It has much higher conjugation efficiency than NBD-Cl and NBD-F. This amine-reactive NBD derivative, containing a convenient succinimidyl ester, can be used to develop environmentally sensitive bioconjugates. NBD is a functional analog of the dinitrophenyl hapten, and its fluorescence is quenched upon binding to anti-dinitrophenyl (anti-DNP) antibodies. The X-spacer separates the fluorescent dye from the protein allowing greater sensitivity and reduced perturbation effects on protein labeling. Spectral properties: lamdaEx=460, lambdaEm=540.
