DETAILS

Description (English)
Caution
May precipitate on storage; redissolve at 50-60 °C.
Other Notes
This form of glyoxal is composed of 3 moles of glyoxal and 2 moles of water in a relatively stable configuration.
Useful as a specific probe for the homopurine strand of DNA as it forms a stable product with guanine residues1; Promotes binding of DNA and RNA to nitrocellulose paper2; Agarose gel electrophoresis of glyoxal denatured RNA with silver staining3; Nucleic acid denaturant4
