Detection of viral sequences of low reiteration frequency by in situ hybridization

Detection of viral sequences of low reiteration frequency by in situ hybridization

M Brahic et al. Proc Natl Acad Sci U S A. 1978 Dec.

Abstract

The sensitivity of in situ hybridization has been increased at least 10-fold by hybridizing in cDNA excess, by increasing the diffusion of the cDNA through the cells, by hybridizing at optimum temperature, and by stabilizing hybrids during autoradiography. Saturation of intracellular RNA with [3H]cDNA has been achieved. The assay is quantitative. In situ hybridization has been used to detect and quantitate visna virus RNA in infected cells. By using [3H]cDNA with specific activity of 2 X 10(8) dpm/micrograms and conditions that reduce background to negligible levels, 10--20 copies of viral RNA per cell can be detected and quantitated after 2 days of autoradiographic exposure.
