Immunocytochemistry/ Immunofluorescence - Anti-IL-6 antibody [EPR20653] (AB214429)

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HUVEC (human umbilical vein endothelial cell line) cells, untreated or treated with Lipopolysaccharides (LPS) (0.5 μg/ml 24 hours) and Brefeldin A (BFA) (300 ng/ml 20 hours), labeling IL6 with ab214429 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing the cytoplasmic expression increased on HUVEC cells treated with Lipopolysaccharides (LPS) (0.5 μg/ml, 24 hours) and Brefeldin A (BFA) (300 ng/ml, 20 hours).

The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) (ab195889) (red) at 1/200 dilution.

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution.

Immunoprecipitation - Anti-IL-6 antibody [EPR20653] (AB214429)

IL6 was immunoprecipitated from 0.35 mg of HUVEC (human umbilical vein endothelial cell line) treated with Lipopolysaccharides (LPS) and Brefeldin A (BFA) whole cell lysate with ab214429 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab214429 at 1/1,000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10,000 dilution

Lane 1 : HUVEC treated with 0.5 μg/ml LPS for 24 hours and 300 ng/ml BFA for 20 hours whole cell lysate 10 μg (Input).

Lane 2 : ab214429 IP in HUVEC treated with 0.5 μg/ml LPS for 24 hours and 300 ng/ml BFA for 20 hours whole cell lysate (+).

Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab214429 in HUVEC treated with 0.5 μg/ml LPS for 24 hours and 300 ng/ml BFA for 20 hours whole cell lysate (-).

Western blot - Anti-IL-6 antibody [EPR20653] (AB214429)

Lanes 1 - 4 : Merged signal (red and green). Green - ab214429 observed at 25 kDa. Red - loading control ab7291 (Mouse anti-Alpha Tubulin [DM1A] observed at 55kDa.

ab214429 was shown to react with IL-6 in wild-type A549 cells in western blot with loss of signal observed in IL-6 knockout cell line ab273751 (knockout cell lysate ab275501). Wild-type and IL-6 knockout A549 cell lysates were subjected to SDS-PAGE. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with ab214429 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 hour at room temperature before imaging.
