Flow Cytometry (Intracellular) - Anti-IL-1 beta antibody [EPR23851-127] - BSA and Azide free (AB282021)

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab254360).

Flow cytometry staining of human peripheral blood mononuclear cells (PBMCs) (top) or PBMCs treated with 1µg/mL LPS and 1µg/mL BrefeldinA for 18 Hours (bottom), with ab254360 (right) or Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control (left).

PBMCs were incubated for 30 min on ice in 1x PBS containing 10 µg/ml human IgG and 10 % normal goat serum to block FC receptors and non-specific protein-protein interactions. Cells were fixed and permeabilised with BD Cytofix/Cytoperm™ for 20 min, followed by addition of the antibody ab254360 or Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control (1x 10⁶ in 100 µl at 0.2 μg/ml (1/2,500)) for 30 min at 22°C .

The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed was incubated at 1/4000 for 30min at 22°C

Acquisition of >30000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter. Events were gated on live cells.

This data was developed using the same antibody clone in a different buffer formulation (ab254360). ab254360 staining IL-1 beta in wild-type THP-1 cells (top panel) and IL1B knockout THP-1 cells (ab273762) (bottom panel) +/- TPA (80nM overnight) and LPS (100ng/ml, 6h). The cells were fixed with 4% paraformaldehyde (10 min) then permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab254360 at 0.4μg/ml concentration and ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor^® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor^® 594) (ab150120) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8).

Western blot - Anti-IL-1 beta antibody [EPR23851-127] - BSA and Azide free (AB282021)

This data was developed using ab254360, the same clone in a different buffer formulation.

Expression of IL-1 beta is induced by LPS treatment. 31-kDa precursor IL-1 beta, 28- and 17.5-kDa proteolytically cleaved IL-1 beta are observed. The expresssion pattern and molecular weight observed is consistent with what has been described in the literature (PMID : 8446594, 19559631).

Compared with ab254360, ab283818 has higher affinity. For better using ab254360, we recommend loading higher amount of human/rat lysate or using lower antibody dilution.
