All lanes : Anti-IL-1 beta antibody [EPR21086] (ab216995) at 1/1000 dilution
Lane 1 : Wild-type THP-1 untreated cell lysate
Lane 2 : Wild-type THP-1 LPS-treated (3 h, 100 ng/ml) cell lysate
Lane 3 : IL1B knockout THP-1 untreated cell lysate
Lane 4 : IL1B knockout THP-1 LPS-treated (3 h, 100 ng/ml) cell lysate
Lysates/proteins at 30 µg per lane.
Performed under reducing conditions.
Predicted band size: 30 kDa
Observed band size: 27-32 kDa why is the actual band size different from the predicted?This data was developed using the same antibody clone in a different buffer formulation (ab216995).
Lanes 1 - 4: Merged signal (red and green). Green - ab216995 observed at 27-32 kDa. Red - loading control ab7291 (Mouse anti-Alpha Tubulin [DM1A]) observed at 55 kDa.
ab216995 was shown to react with IL-1 beta in wild-type THP-1 cells in Western blot with loss of signal observed in IL1B knockout sample. Wild-type THP-1 and IL1B knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween®) before incubation with ab216995 and ab7291 (Mouse anti-Alpha Tubulin [DM1A]) 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.

IL-1 beta was immunoprecipitated from 0.35 mg THP-1 (human monocytic leukemia monocyte) whole cell lysate treated with 100 ng/ml lipopolysaccharide (LPS) for 3 hours, with ab216995 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab216995 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.
Lane 1: THP-1 (human monocytic leukemia monocyte) treated with 100 ng/ml lipopolysaccharide (LPS) for 3 hours whole cell lysate 10 µg (Input).
Lane 2: ab216995 IP in THP-1 treated with 100 ng/ml lipopolysaccharide (LPS) for 3 hours whole cell lysate (+).
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab216995 in THP-1 treated with 100 ng/ml lipopolysaccharide (LPS) for 3 hours whole cell lysate (-).
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 3 minutes.This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab216995).
