Descrizione

Applicazioni

Stains-All has been used for the staining of gel made for size determination of hyaluronan.[1][2] It has also been used for the staining of DNA oligonucleotides separated by nondenaturing polyacrylamide gel electrophoresis.[3]

Azioni biochim/fisiol

Stains-All is a cationic carbocyanine dye and is a multipurpose dye. It stains sialoglycoproteins blue, Ca²⁺ binding proteins deep blue to violet, proteins red and lipids yellow-orange.[4] It also stains RNA (bluish purple) and DNA (blue).[5]

As little as 3 ng (123 BP fragment) of pBR322/Hae III digest DNA and 90 ng tRNA can be detected on a polyacrylamide gel. PAGE gels are stained in the dark and then destaining by removing the gel from the staining solution and exposing it to the light from a light box until sufficient destaining has occurred. A staining solution is typically made by dissolving the dye in formamide and buffer.

Avvertenza

Upon continued exposure to light the nucleic acid-dye complex will fade and disappear.
