설명

일반 설명

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

애플리케이션

Suitable for

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

기타 정보

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.

주의사항

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

원리

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