Clone EPR4118 (ab220823) has been successfully conjugated by Abcam. This image was generated using Anti-PGP9.5 antibody [EPR4118] (Alexa Fluor® 647). Please refer to ab196173 for protocol details.

IHC image of PGP9.5 staining in a section of formalin-fixed paraffin-embedded normal human pancreas*.

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 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 ab196173 at 1/100 (shown in red) and counterstained using ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 488), at 1/250 dilution (shown in green). 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.
