DescriptionSUMO-2 modified with biotin via primary amine coupling resulting in modification of lysine residues as well as the N-terminus. Although having a fully functional C-terminus, lysine modification may limit the ability of this reagent to propagate poly-SUMO chains. Biotinylated SUMO-2 can be detected using avidin-linked reagents for higher efficiency and sensitivity than with antibodies.Molecular Weight (kDa)10.6 kDaFormulation50 mM HEPES pH 8.0, 150 mM NaCl, 1mM DTT, 10% glycerolSourceExpressed in E.coli expression systemSize50 µgStorage Temp & ConditionsStore at -80°C.
