WebDeionized glyoxal may be prepared by passing a 40% (6 M) solution through a mixed bed resin column until the pH exceeds 5.0. 2. Incubate 10–15 μg total cellular RNA in 15–20 μl denaturation buffer for 1 hr at 50°C. When rare messages are to be detected, up to 3 μg poly (A)+ RNA can be substituted. WebGlyoxal offers some benefits over traditional triazine chemistry as an H2S scavenger [2]. Glyoxal is effective and can be applied in neutral, acidic, and alkaline conditions (pH environment), where triazine is effective and stable only under alkaline conditions. An acidic formulation allows the product to avoid causing carbonate scaling.
