ASM24-Beads

As part of the Signal-Seeker™ product line, SUMOylation 2/3 affinity beads have been optimized in order to detect endogenous levels of SUMO 2/3 modified proteins, which often represent <1% of the target protein. SUMOylation 2/3 affinity beads comprise an anti-SUMO-2/3 antibody (Clone 11G2) that has been chemically conjugated to Protein G beads. Validation studies done in Hela cells have shown that these beads can immunoprecipitate a wide range of SUMO 2/3 modified proteins without detectable leaching of either heavy or light chains in an IP assay. A comprehensive Signal-Seeker™ SUMOylation 2/3 Detection Kit is also available (BK162) and is recommended for first time users.

Validated Applications

Immunoprecipitation using the Signal-Seeker™ SUMOylation 2/3 Detection Kit

Denatured cell lysates were prepared as previously reported1 from HeLa cells ("HS43": Heat Shock treated 42°C  for 10 min, and "CT37": untreated) and HeLa siRNA SUMO knockdown ("KDS2"). 1mg of lysate was used for the immunoprecipitation (IP) of SUMOylated 2/3 proteins. Western blots of immunoprecipitated proteins were developed using anti-SUMO-2/3 antibody (Cytoskeleton cat# ASM23) (A) or anti-Ubc9 antibody (B). The level of SUMO-2/3 conjugates in heat shock treated cells is higher than control, and shRNA SUMO-2 knock-down reduced the level of SUMOylated 2/3 modified proteins. Chemical conjugation of SUMO-2/3 antibody (11G2) to the affinity bead matrix prevents heavy and light chain leaching. Unconjugated free SUMO is also captured by the SUMO-2/3 affinity beads.

(B) Unmodified Ubc9 is visible near 18kDa. High molecular-weight band indicates that Ubc9 is SUMOylated by a single SUMO-2/3 protein. Ubc9 has previously been reported to be a target for SUMOylation1,2
