Spinlabeling of oligonucleotides with nitroxides is hampered by their intrinsic instability under conditions of solid-phase synthesis and enzymatic ligation. Although nitroxide decomposition can be avoided in some cases by postsynthetic introduction or by special reaction conditions, a more general solution would be reversible protection of the radical. We have recently developed such a method based
