Proximity labelling is a laboratory technique which makes it possible to label proteins (in this case by biotinylation), proximal to protein of interest. This allows studying protein interactome networks in different types of cells and organs, as well as different developmental stages. The technique is achieved by a gene fusion in a living cell, between the protein of interest and BioID (BirA). The TurboID variant is a biotin ligase, with substantially higher activity, which provides higher temporal resolution and broader application in vivo. The labelling time is just 10 minutes in RT, compared to the over 18 hours of labelling time required for BioID. 

Agrisera offers a new polyclonal antibody, prepared to a recombinant mutated BirA protein from E.coli, called TurboID.
