Recombinant human perforin.
Our Abpromise guarantee covers the use of ab47225 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Predicted molecular weight: 70 kDa.|
|Flow Cyt||Use at an assay dependent concentration. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.|
|IHC-Fr||Use a concentration of 20 µg/ml.|
|IHC-P||Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
IHC image of Perforin staining in human spleen 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 with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab47225, 10µg/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.
