Quality Control Protein Identification: n/a  
Quality Control Activity: Identification of Polyubiquitin Chains in Lysate:  A Western blot of IL-1 stimulated HEK293 cell lysate (lane 2) and non-stimulated HEK293 cell  lysate (lane 3) probed with an anti-FK2 antibody indicates that both of the lysates are abundant  with ubiquitylated proteins and possibly free ubiquitin chains. Polyubiquitin (Ub2-7) (K63-linked)  was included as a positive control in this experiment (lane 1).
