DNA-RNA Hybrid antibody tested by dot blot.
23-mer DNA, RNA or DNA-RNA Hybrid samples were spotted (indicated in ng on the left) on to a positively charged nylon membrane and blotted with DNA-RNA Hybrid antibody at 1 µg/ml dilution.

DNA-RNA hybrids are a natural occurrence within eukaryotic cells, with levels of these hybrids increasing at sites with high transcriptional activity, such as during transcription initiation, repression, and elongation. Because RNA-DNA hybrids influence genomic instability, the S9.6 antibody is a useful reagent to help study the consequences of R-loops and lesions formed by these hybrids during DNA replication or other cellular processes. In addition, the S9.6 antibody is effective in recognizing RNA-DNA hybridization for microarray studies.
