Abstract
The specificity of the probe for intracellular RNA during hybridization histochemistry is usually confirmed by loss of the signal following ribonuclease pre-treatment of the target. Interpretation of such controls is complicated when single-stranded (asymmetric) RNA probes (riboprobes) are used for in situ hybridization, since the probes themselves may be degraded by residual ribonuclease. A protocol using the Ca2+-dependent enzyme, micrococcal nuclease, is presented to circumvent these difficulties.
