A novel method to measure mRNA levels has been developed by combining the
detection capabilities of RNase protection (RPA) with the quantification
advantages of scintillation proximity assay (SPA) technology. Sample
processing is reduced to the addition of a single reagent post RNase
digestion. As a model system, the inducible expression of rat
apolipoprotein-A1 mRNA has been measured by both traditional gel-based RPAs
and the SPA-based RPA assay. Results demonstrate that the ribonuclease
protection proximity assay (RiPPA) faithfully reproduces the gel-based
results and is at least as sensitive as many existing methods.
