Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Synaptic Marker (Synaptophysin, Synapsin1, PSD95, VAMP2) Antibody Sampler Panel - Human, Mouse (AB263463)

Immunohistochemical staining of paraffin embedded human pancreas with purified ab32127 at a dilution of 1/400.

A pre-diluted HRP polymer for rabbit/mouse IgG was used as the secondary antibody and the sample was counterstained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0.

PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Synaptic Marker (Synaptophysin, Synapsin1, PSD95, VAMP2) Antibody Sampler Panel - Human, Mouse (AB263463)

IHC image of PSD95 [K28/43] staining in Human normal cerebral cortex formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval (EDTA based pH 9.0 solution, epitope retrieval solution 2) for 20 mins. The section was then incubated with ab192757, 0.05μg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

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