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.[1] 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.
