Methods to fix and detect nucleic acids

Abstract

In one aspect, the invention relates to a method for fixing a short nucleic acid in a biological sample. In another aspect, the invention relates to a method for detecting a target short nucleic acid in a biological sample. The method includes contacting the biological sample with an aldehyde-containing fixative, and subsequently contacting the sample with a water-soluble carbodiimide. In a further aspect, the invention relates to a kit for fixing a short nucleic acid in a biological sample. The kit includes a support substrate for holding the sample; an aldehyde-containing fixative; and a water-soluble carbodiimide.
