  • Lewis rat bone marrow cells stained with ab243850 (right) or mouse IgG1κ (ab170190) isotype (left). Lewis rat bone marrow cells were incubated for 30 min on ice in 1x PBS / 10 % rat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab243850) or mouse IgG1κ (ab170190) (1x106 in 100 µl at 0.2 µg/ml) for 30 min on ice.

    The secondary antibody Goat anti-mouse IgG H&L (Alexa Fluor ® 488, pre-adsorbed) (ab150117) was used at 1/2000 dilution for 30 min on ice. The cells were simultaneously stained with Ter-119 antibody.

    Acquisition of >30,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter. Events were gated on viable cells

  • IHC image of Endothelium, macrophages and red blood cells staining in a section of frozen normal Rat Lung.

    The section was fixed using 10% formaldehyde in 1XPBS for 10 minutes. No antigen retrieval step was performed prior to staining. Non-specific protein-protein interactions were then blocked in TBS containing 0.025% (v/v) Triton X-100, 0.3M glycine and 1% (w/v) BSA for 1h at room temperature.  The section was then incubated overnight at +4°C in TBS containing 0.025% (v/v) Triton X-100 and 1% (w/v) BSA with ab243850 at 1µg/ml. The section was then incubated with ab150117 (Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) preabsorbed, (Shown in green) 1/1000) for 1 hour at room temperature. DAPI was used to stain the cell nuclei (blue). The secondary-only control insert image is taken from an identical assay without primary antibody. The section was then mounted using Fluoromount®.

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

    For IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antibody concentrations and incubation times.
