5(6)-TAMRA-X, SE

Product ID: M4102

Unit SizePriceQuantity 
10 mg

Availability: In stock


Amine-Reactive form of TAMRA, SE for labeling olignucleotides and automated DNA sequencing applications.

This probe contains a 7-atom spacer (X) between the reactive group and the fluorophore which helps to separate the fluorophore from the conjugated biomolecule making it more accessible to secondary detection reagents.
