Goat anti rabbit immunoglobulin g

Thoracic aortic tissues isolated at different stages were fixed in 4% paraformaldehyde and permeabilized using 0.1% Triton X-100 at room temperature and then blocked by 5% BSA. Slides were incubated with polyclonal rabbit anti-rat chemerin (1 : 1000, Abcam, UK). Subsequently, tissues were treated with goat anti-rabbit immunoglobulin G (1 : 500, Invitrogen Life Technologies, USA) and stained by 4′,6-diamidino-2-phenylindole (DAPI). The confocal microscope (Leica, Germany) was employed to capture fluorescence images. All parameters were measured by computer-assisted color image analysis.

For detection of ArnC and ArnD, the cytosolic and membrane fractions were used. For detection of FlaB and FlaX, ArnA and ArnB, samples were taken, centrifuged at 4,100g, and resuspended in 100 mmol/L KCl, 50 mmol/L HEPES pH 8.0 to an OD₆₀₀ of 3. Samples were heated to 100°C for 5 min and separated by SDS‐PAGE using 11% gels. Subsequently, proteins were transferred onto PVDF membrane (Roche) applying a semidry method. Equal loading of gels was confirm by staining with InstantBlue (Expedeon). For the detection of FlaB and FlaX (Lassak et al., 2012), ArnA, ArnB (Reimann et al., 2012) primary polyclonal antibodies were used in a dilution of 1:400, 1:800, 1:5,000, and 1:5,000, respectively. Primary antibodies directed against the HA‐tag were obtained from Sigma and used 1:10,000 diluted. As a secondary antibody 1:10,000 diluted goat‐anti‐rabbit immunoglobulin G coupled to HRP (Invitrogen) was applied to the membranes. Chemiluminescent signals were detected with an ECL chemocam imager (Intas) using WesternSure ECL Substrate (LI‐COR). Quantification of Western blots was performed using Image J (Schneider, Rasband, & Eliceiri, 2012).
