ab237354 staining TNF alpha in RAW 264.7+/-100 ng/ml lipopolysaccharides (LPS) for 7 hours with addition of 1 μg/ml brefeldin A (BFA) for the last 3 hours. The cells were fixed with 4% formaldehyde (10 min), 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 overnight at +4°C with ab237354 at 1/100 dilution (shown in red) and ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labeled with DAPI (shown in blue).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

Overlay histogram showing RAW264.7 cells treated (red line) or untreated (green line) with 100 ng/mL of lipopolysaccharides (LPS) for 7 hours with addition of 1 μg/mL brefeldin A (BFA) for the last 3 hours and subsequent staining with ab237354. The cells were fixed with 4% formaldehyde and then permeabilized with 90% methanol. The cells were then incubated in 1x PBS containing 10% normal serum to block non-specific protein-protein interactions followed by the antibody (ab237354) (1x106 in 100μl at 1/500 dilution (1 μg/ml)) for 30 min at 22°C.

Isotype control antibody (black line) was Rabbit IgG (monoclonal) Alexa Fluor® 647 (ab199093) used at the same concentration and conditions. Unlabeled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 17 mW Red laser (633 nm) and 660/20 bandpass filter.

Target data

Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation (By similarity). Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance (PubMed : 25586176). Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6 (By similarity). Promotes osteoclastogenesis and therefore mediates bone resorption (PubMed : 32741026).. The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.
