Recombinant Alexa Fluor® 647 Anti-NeuN antibody [EPR12763] - Neuronal Marker (ab190565)

IHC image of ab190565 staining in formalin fixed paraffin embedded tissue section of normal human cerebellum.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6) in a Dako Pascal pressure cooker using the standard factory-set regime. Non-specific protein-protein interactions were then blocked using in TBS containing 0.025% (v/v) Triton X-100, 0.3M (w/v) glycine and 3% (w/v) BSA for 1h at room temperature. The section was then incubated with ab190565 (1/50) in TBS containing 0.025% (v/v) Triton X-100 and 3% (w/v) BSA overnight at +4°C. The section was then counterstained and mounted with SlowFade^® Gold Antifade Mountant with DAPI.

The DAPI only control (no antibody) inset shows no autofluorescence, demonstrating that any Alexa Fluor^® 647 signal is dervied directly from bound ab190565. The separate images of ab190565 and DAPI alone, combined with the merged version of both signals, shows predominant co-localisation of the Alexa Fluor^® 647 signal in the nuclei of the cerebellar granule layer.

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

ab190565 staining NeuN in U87-MG cells. The cells were fixed with 100% methanol (5min) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab190565 at 1/50 dilution(shown in red) and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin) at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1h with an Alexa Fluor^® 488 Goat anti-Mouse secondary (ab150117) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

Effects of delayed treatment of L655,708 on neurogenesis in the peri-infarct region. Ki67, a proliferative marker, and NeuN, a neuronal marker, were used to evaluate neurogenesis in the peri-infarct region. The nuclei were counter-stained with DAPI. Asterisk represents the significant difference from vehicle (n = 8/group; p < 0.05). Pond represents the significant difference from 1 mg group (n = 8/group; p < 0.05). Scale bar = 25 µm.

Panel A shown only. Rat brain sections were first pre-treated with citrate buffer (0.01 mol/L, pH 6.0) for 5 minutes at 85 °C, followed by incubation with 5% normal goat serum for 1 hour at room temperature. Sections were then incubated with anti-Ki67 (rabbit monoclonal antibody to Ki67, 1/500; ab16667) and anti-NeuN (rabbit monoclonal antibody to NeuN, 1/500; ab190565), overnight at 4°C. Sections were then rinsed in phosphate-buffered saline 3 times, followed by incubation with rabbit secondary antibody (anti-rabbit IgG, 1/1000) for 1 hour at room temperature. Fluorescence signals were then detected under a microscope. Negative control was conducted by incubating sections with PBS instead of primary antibodies. No positive signals were shown in negative control.

The cells were fixed with 100% methanol (5min) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab190565 at 1/50 dilution (shown in red) and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin) at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1h with an Alexa Fluor^® 488 Goat anti-Mouse secondary (ab150117) at 2 μg/ml (shown in green).

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6) in a Dako Pascal pressure cooker using the standard factory-set regime. Non-specific protein-protein interactions were then blocked using in TBS containing 0.025% (v/v) Triton X-100, 0.3M (w/v) glycine and 3% (w/v) BSA for 1h at room temperature. The section was then incubated with ab190565 (1/50) in TBS containing 0.025% (v/v) Triton X-100 and 3% (w/v) BSA overnight at +4°C. The section was then counterstained and mounted with SlowFade^® Gold Antifade Mountant with DAPI.
