Total cell lysates and nuclear and cytoplasmic extracts were prepared from sorted and/or treated CD11c+ and CD11c cells as described in text using lysis buffer (Cell signaling) and nuclear extraction kit (Panomics), respectively. Lysates (15 µg) were separated on 10% SDS-PAGE gels and then transferred onto PVDF membranes (Millipore). Nonspecific binding was blocked by incubation in blocking buffer (5% nonfat milk in TBST), followed by sequential incubations with the primary antibody and appropriate horseradish peroxidase-conjugated secondary antibody (Thermo Scientific), each diluted in blocking buffer. Immunoreactive protein was detected using enhanced chemiluminescence (ECL) reagents (Thermo Scientific). Antibodies against κBα (Santa Cruz biotech), phospho-IκBα, NF-κB subunit p65, c-rel, LSD1 (Cell Signaling), phospho IKKα/β, IKKα/β (Cell Signaling), MnSOD (EMD Millipore), Cu-ZnSOD (Enzo lifesciences) and β-actin (Cell signaling) were used for western blot analysis.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
