Description

1-Oxyl-2,2,5,5-tetramethylpyrroline-3-carboxylate NHS ester is an N-hydroxysuccinimide ester of the nitroxide spin label 2,2,5,5-tetramethyl-3-carboxylpyrrolin-1-oxyl, also known as tempyo. This ester is an active acylating agent that preferentially targets α-amino groups. This reagent can be used to spin label proteins and aminoacylated RNA species.
