Compounds and processes for single-pot attachment of a label to siRNA

摘要

Compounds and methods are provided for a single-pot covalent attachment of a label to an siRNA comprising forming a covalently attachable labeling reagent for alkylating the molecule. Then, combining the covalently attachable labeling reagent with a mixture containing the molecule, under conditions wherein the labeling reagent has reactivity with the molecule thereby forming a covalent bond.
