Clone MJFR-14-6-4-2 (ab214033) has been successfully conjugated by Abcam. This image was generated using Anti-Alpha-synuclein aggregate antibody [MJFR-14-6-4-2] - Conformation-Specific (Alexa Fluor® 488). Please refer to ab216124 for protocol details.

IHC image of alpha-synuclein aggregate staining in a section of frozen Parkinson human substantia nigra*.

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 (w/v) 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 ab216124 at 1/100 dilution (shown in green) and counterstained using ab195884, Rat monoclonal to Tubulin (Alexa Fluor^® 647), at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Fluoromount^®.

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

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

ab209538 staining Alpha-synuclein aggregate in Human DLB brain tissue sections by Immunohistochemistry (Formalin/PFA fixed paraffin embedded sections). Tissue was fixed with paraformaldehyde and blocked with 2% BSA for 10 minutes at 21°C; antigen retrieval was by heat mediation in Citric acid. Samples were incubated with primary antibody (1/10,000 in TBS) for 2 hours at 21°C. A biotin conjugated anti-rabbit IgG Goat polyclonal was used as the secondary antibody at 1/300 dilution.

IHC image of alpha-synuclein aggregate staining in a section of formalin-fixed paraffin-embedded Parkinson human substantia nigra*.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6) in a Biocare Medical NxGen pressure cooker using retrieval settings of 110^oC for 8 minutes. Non-specific protein-protein interactions were then blocked in TBS containing 0.025% (v/v) Triton X-100, 0.3M (w/v) 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 ab216309 at 1/5000 dilution (shown in red) and counterstained using ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 488), at 1/250 dilution (shown in green).

Lane 3 : Untreated recombinant alpha-synuclein filament.

Lane 4 : Untreated recombinant alpha-synuclein filament.

Alpha Synuclein filaments were generated using full length recombinant alpha-synuclein (aa1-140) by incubation in 20mM TRIS, pH 7.2 at 37 °C with agitation.

Denaturation of filaments with 70% formic acid reduces antibody recognition by 30-100 fold, demonstrating conformation specificity.
