Beschreibung

General description

Photobiotin acetate is made up of biotin, which is bound with the help of a charged linker arm to a photoreactive arylazide group.

Application

Photobiotin acetate salt has been used to label DNA probes to perform DNA−DNA hybridization to determine genomic relatedness.

Biochem/physiol Actions

Photobiotin is a photo-activatable analog of biotin used primarily for labeling DNA, RNA and proteins. Probes prepared using photobiotin can detect target DNA as little as 0.5 pg.

Photobiotin acetate is capable of labeling single stranded DNA and linear or supercoiled double-stranded DNA.

Disclaimer

Light sensitive.
