Merck, PAT001-100UG, Protein A-Turbo - Proximity Biotinylation Enzyme

General description
Protein A Turbo is a recombinantly expressed Protein A-TurboID fusion protein with the capability to bind IgG through the Protein A region, and enzymatically biotinylate proximal proteins non-specifically with the TurboID region.
Application
