A flexible, low-cost alternative to FISH, primed in situ labeling (PRINS) has traditionally been used to detect tandemly repeated target sequences in chromosomes and nuclei. The technique is capable of discriminating among closely related DNA sequences in situ and has the advantage of using very small probes which easily penetrate to almost any target. This unit describes basic PRINS and the alternative version, dideoxy-PRINS, which can increase the sensitivity of the reaction by an order of magnitude. New material on multicolor PRINS and quantitative PRINS has been added. Protocols for detection of single-copy sequences and for application to the study of in-vivo activity of DNA-modifying enzymes are planned.
