QA; ActivityIdentification 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).
HEK293 Cell Lysate (IL-1 stimulated) may be used to demonstrate the ability of ubiquitin binding domain proteins (Optineurin and NEMO) to capture polyubiquitylated proteins including IL-1 receptor-associated kinase 1 (IRAK1) (Windheim et al. 2008).
