This purified polyclonal antibody reacts with human SUMO-3 by western blot and ELISA. Although not tested, this antibody is likely functional in immunohistochemistry and immunoprecipitation. This antibody using the specified conditions may recognize other prominent intrinsic bands (UBLs or conjugates). Other intrinsic bands are readily detectable at lower dilutions. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 11.6 kDa in size corresponding to human SUMO-3 by western blotting in the appropriate cell lysate or extract.
