Western blot analysis of CD23/FCER2 using anti-CD23/FCER2 antibody (PB9051). The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: rat thymus tissue lysates,
Lane 2: rat brain tissue lysates,
Lane 3: rat PC-12 whole cell lysates,
Lane 4: mouse spleen tissue lysates,
Lane 5: mouse thymus tissue lysates,
Lane 6: mouse brain tissue lysates,
Lane 7: mouse RAW264.7 whole cell lysates.
After electrophoresis, proteins were transferred to a membrane. Then the membrane was incubated with rabbit anti-CD23/FCER2 antigen affinity purified polyclonal antibody (PB9051) at a dilution of 1:1000 and probed with a goat anti-rabbit IgG-HRP secondary antibody (Catalog # BA1054). The signal is developed using ECL Plus Western Blotting Substrate (Catalog # AR1197). A specific band was detected for CD23/FCER2 at approximately 45 kDa. The expected band size for CD23/FCER2 is at 38 kDa.

IHC analysis of CD23/FCER2 using anti-CD23/FCER2 antibody (PB9051).
CD23/FCER2 was detected in a paraffin-embedded section of human tonsil tissue. Biotinylated goat anti-rabbit IgG was used as secondary antibody. The tissue section was incubated with rabbit anti-CD23/FCER2 Antibody (PB9051) at a dilution of 1:200 and developed using Strepavidin-Biotin-Complex (SABC) (Catalog # SA1022) with DAB (Catalog # AR1027) as the chromogen.

The tissue section was incubated with rabbit anti-CD23/FCER2 Antibody (PB9051) at a dilution of 1:200 and developed using Strepavidin-Biotin-Complex (SABC) (Catalog # SA1022) with DAB (Catalog # AR1027) as the chromogen.

IF analysis of CD23 using anti-CD23 antibody (PB9051)
CD23 was detected in paraffin-embedded section of mouse lymphaden tissues. Heat mediated antigen retrieval was performed in citrate buffer (pH6, epitope retrieval solution ) for 20 mins. The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1μg/mL rabbit anti-CD23 Antibody (PB9051) overnight at 4°C. Fluoro488 Conjugated Goat Anti-Rabbit IgG (BA1127) was used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37°C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

Flow Cytometry analysis of mouse BMC cells using anti-CD23/FCER2 antibody (PB9051).
Overlay histogram showing mouse BMC cells stained with PB9051 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-CD23/FCER2 Antibody (PB9051) at 1:100 dilution for 30 min at 20°C. Fluoro488 conjugated goat anti-rabbit IgG (BA1127) was used as secondary antibody at 1:100 dilution for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG at 1:100 dilution used under the same conditions. Unlabelled sample without incubation with primary antibody and secondary antibody (Red line) was used as a blank control.
