DNA and RNA Detection

UV Shadowing

Detection of DNA/RNA in solution is generally done by measuring its UV absorbance at 260 nm.

Post-Electrophoretic Visualization with Nuclistain

National Diagnostics' Nuclistain offers a significant increase in sensitivity over UV shadowing,

Ethidium Bromide Staining

The most commonly used stain for detecting DNA/RNA is ethidium bromide.

Silver Staining DNA Gels

Silver staining is more sensitive than ethidium bromide for double stranded DNA, and detects single stranded DNA or RNA with no loss in sensitivit

An Overview of Northern and Southern Blotting

A DNA or RNA probe will selectively hybridize with nucleic acid molecules of complementary sequence in a sample.
