Polynucleotide hybridization probes
First Claim
Patent Images
1. A method for preparing a polynucleotide hybridization probe which comprises selectively protecting a probe region within a single stranded polynucleotide having a probe region and a non-probe region both 5'"'"' and 3'"'"' to the probe region by hybridizing the probe region to a complementary sequence and then chemically modifying the non-probe region of the remaining single-stranded portion of the polynucleotide.

Abstract
Polynucleotide hybridization probes are labeled in non-probe regions but not in probe regions by selectively protecting probe regions prior to modification of the polynucleotide.
