Immunoprecipitation - Anti-ATG4B antibody [EPR16572] (AB199537)

ATG4B was immunoprecipitated from 1mg of Ramos (Human Burkitt's lymphoma cell line) whole cell lysate with ab199537 at 1/60 dilution. Western blot was performed from the immunoprecipitate using ab199537 at 1/500 dilution (Panel A) or ab154843 at 1/500 dilution (Panel B). Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution.

Lane 1 : Ramos whole cell lysate 10ug (Input). Lane 2 : ab199537 IP in Ramos whole cell lysate. Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab199537 in Ramos whole cell lysate.

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

Exposure time : Panel A and B 30 seconds.

Immunoprecipitation - Anti-ATG4B antibody [EPR16572] (AB199537)

ATG4B was immunoprecipitated from 1mg of Jurkat (Human T cell leukemia cells from peripheral blood) whole cell lysate with ab199537 at 1/50 dilution. Western blot was performed from the immunoprecipitate using ab199537 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution.

Lane 1 : Jurkat whole cell lysate 10ug (Input). Lane 2 : ab199537 IP in Jurkat whole cell lysate. Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab199537 in Jurkat whole cell lysate.

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

Western blot - Anti-ATG4B antibody [EPR16572] (AB199537)

Lanes 1 - 2 : Merged signal (red and green). Green - ab199537 observed at 47 kDa. Red - loading control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37kDa.
ab199537 was shown to react with ATG4B in wild-type HeLa cells in Western blot with loss of signal observed in ATG4B knockout cell line ab260973 (ATG4B knockout cell lysate ab257364). Wild-type and ATG4B knockout HeLa cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween^®) before incubation with ab199537 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4 ^°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

ab199537 was shown to specifically react with ATG4B when ATG4B knockout samples were used. Wild-type and ATG4B knockout samples were subjected to SDS-PAGE. ab199537 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed ab216776
