General description

Glyoxal is a nucleic acid denaturant. It acts as a specific probe for homopurine strands of DNA.

Application

Suitable for
  • nucleic acid denaturation
  • binding of DNA/RNA to nitrocellulose membrane

Other Notes

This form of glyoxal is composed of 3 moles of glyoxal and 2 moles of water in a relatively stable configuration.
May precipitate on storage; redissolve at 50-60 °C.

Caution

May precipitate on storage; redissolve at 50-60 °C.

Principle

Glyoxal forms stable complex with guanine residues that results in denaturation of nucleic acids.
