Immunoprecipitation - Anti-SQSTM1 / p62 antibody [3/P62 LCK LIGAND] - Autophagosome Marker (AB280086)

SQSTM1 / p62 was immunoprecipitated from 0.35 mg HeLa (human cervix adenocarcinoma epithelial cell ), whole cell lysate 10 ug with ab280086 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab280086 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.

Lane 1 : HeLa (human cervix adenocarcinoma epithelial cell ), whole cell lysate 10 ug

Lane 2 : ab280086 IP in HeLa whole cell lysate

Lane 3 : Mouse monoclonal IgG1(ab18443) instead of ab280086 in HeLa whole cell lysate

Blocking and dilution buffer and concentration : 5% NFDM/TBST.

Exposure time : 26 seconds

Blocking and diluting buffer and concentration : Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS

Lanes 1 - 4 : Merged signal (red and green). Green - ab280086 observed at 62 kDa. Red - loading control ab181602 (Rabbit monoclonal [EPR16891] to GAPDH) observed at 36 kDa.

Lanes 1-2 : ab280086 Anti-SQSTM1/p62 antibody was shown to react with SQSTM1 in HAP1 cells in Western blot. Loss of signal was observed when SQSTM1 knockout sample was used. Wild-type and SQSTM1 knockout samples were subjected to SDS-PAGE. ab280086 and Anti-GAPDH antibody [EPR16891] - Loading Control (ab181602) were incubated at 4°C overnight at 1/1000 dilution and 1/20000 dilution respectively.

Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 680CW) preadsorbed (ab216777) and Goat anti-Mouse IgG H&L (IRDye® 800RD) preadsorbed (ab216772) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.
