Control Agarose Beads (negative control) - 400 µL

For use in “pre-clearing” cell lysates, as well as a negative control for the pulldown of polyubiquitylated proteins in conjunction with agarose-conjugated TUBEs (UM401 and UM402). Control Agarose is generated by blocking an activated matrix (identical to that used for TUBEs conjugation) with ethanolamine. Control Agarose (200µl resin) is supplied as a 50% slurry in PBS, pH 7.2, 20% ethanol.
