Anti-Adiponectin antibody [19F1] (ab22554)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) of Mouse Adipose tissue staining Adiponectin using ab22554 (PBS in negative control) at 1:200 (5μg/ml). ImmunoHistoProbe one step HRP Polymer (ready to use) used. Performed heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0)

ab22554 staining Adiponectin in 3T3-L1 cells (ATCC® CL-173 TM). Increased expression of Adiponectin correlates with adipocyte phenotype, as described in literature. Cells, grown to confluency in DMEM with 10% FBS, were differentiated by stimulation for two days with 0.5 mM 3-isobutyl-1-methylxanthi​ne (ab120840), 0.25uM dexamethasone (ab120743) and 1ug/ml insulin (ab123768), followed by two more days with only insulin. Cells were maintained for an additional three days in growth medium alone. Undifferentiated and differentiated adipocytes were fixed with 100% methanol (5min) at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 1h at room temperature. Staining of the treated cells with ab22554 (2.5µg/ml) and ab6046 at 1µg/ml overnight at +4°C, was followed by a further incubation at room temperature for 1h with an AlexaFluor®488 Goat anti-Rabbit secondary (ab150081) at 2 µg/ml (shown in green) and AlexaFluor®594 Goat anti-Mouse secondary (ab150120) at 2 µg/ml (shown in pseudo colour red). Nuclear DNA was labelled in blue with DAPI. Negative controls: 1– Rabbit primary and anti-mouse secondary antibody; 2 – Mouse primary antibody and anti-rabbit secondary antibody. Controls 1 and 2 indicate that there is no unspecific reaction between primary and secondary antibodies used.

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