SUMO-2/3 affinity beads comprise a SUMO-2/3 antibody (Clone 11G2) that has been chemically conjugated to Protein G beads. The affinity-bead have been shown to immunoprecipitate a wide range of SUMO-2/3 targeted proteins in HeLa cell lysate. The bead reagent has been optimized to give no detectable leaching of either heavy or light chains in an IP assay, making the resulting data extremely clean.
Each lot of affinity-bead is quality controlled to provide high batch to batch consistency, see COA documents.
