WebFeb 24, 2024 · Biotin affinity purification of modified proteins, followed by cleavage of the affinity tag leads to release of natively-mono-ubiquitinated substrates. As proof-of-principle, we applied this method to several substrates of mono-ubiquitination in the Fanconi anemia (FA)-BRCA pathway of DNA interstrand crosslink repair. WebBiotin-Tagged Purification. An assortment of reagents for the purification of biotin labelled proteins are available from G-Biosciences. For single step, small and large scale affinity purifications try Immobilized Avidin Resin. With similar binding to biotin as avidin but less non-specific binding we offer Immobilized Streptavidin Resin.
