stringency


stringency
(= low stringency; high stringency; stringency wash)
In nucleic acid hybridization, the labelled probe is used to label matching sequences by base-pairing. Unbound probe is removed though a series of stringency washes. Low stringency washing (low temperature, high ionic strength), allows some mismatching of probe and target, and thus allows the detection of similar sequences at some cost in specificity. By contrast, high stringency conditions allow only closely matching sequence to remain base-paired.
