SUMO-1 (human), (recombinant) (biotin conjugate)
A useful reagent for studying SUMOylation in vitro. Represents a readily detectable alternative to radio-iodinated SUMO-1. Biotinylated SUMO-1 is activated by SUMO E1, a competent substrate for the SUMO E2 conjugating enzyme Ubc9. Can be conjugated to target proteins, in either a SUMO E3 ligase dependent or independent manner, as appropriate. The biotinyl moiety also provides a potential route to affinity purification of conjugated substrates (or thiol ester-linked enzymes) on avidin/streptavidin matrices. Suggested uses: 1. Ready detection of SUMO-1 modification of specific proteins in vitro. 2. Demonstration that novel proteins are potential targets for SUMOylation under in vitro conditions. 3. Purification of SUMO1-conjugates via streptavidin affinity chromatography.
