Abstract
Novel oligonucleotide probes are provided having the structure ##STR1## wherein: R.sup.2 is lower alkyl; R.sup.3 is C.sub.1 -C.sub.12 alkylene containing 0 to 6 linkages selected from the group consisting of --O--, --S-- and --NR.sup.12 -- wherein R.sup.12 is hydrogen or lower alkyl; R.sup.5 is hydrogen or lower alkyl; R.sup.6 is selected from the group consisting of hydrogen, methyl, bromo and iodo; R.sup.7 is C.sub.1 -C.sub.12 alkylene containing 0 to 6 linkages selected from the group consisting of --O--, --S-- and --NR.sup.12 --, and bound to R.sup.8 through an --O--, --S-- or --NR.sup.12 -- moiety; and R.sup.8 is a protecting group that can be removed and replaced, without affecting the remainder of the compound, by reduction with a reducing agent. Methods for using the probes are provided as well.
