Abstract
The quantitative measurement of steady-state mRNA levels is fundamental to the analysis of gene expression. A variety of techniques are widely used to achieve this including Northern blotting, RNase protection, and S1 nuclease protection. We describe here in detail a relatively recent extension of the S1 nuclease protection technique (1) in which radiolabeled oligonucleotides are used as probes in a solution hybrieization assay (2). The principle advantage of this technique is that it allows, in a single RNA sample, the simultaneous measurement of the relative levels of at least six mRNA species, including that of a control mRNA. Further, a large number of RNA samples can be analyzed at one time.
