IHC image of Wnt3a staining in mouse placenta formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol B. 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 ab19925, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated ABC 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
Western blot - Wnt3a antibody (ab19925)
Anti-Wnt3a antibody (ab19925) at 1 µg/ml + Recombinant mouse Wnt3a, AAs 19-352 with a 16 AA n-terminal non-Wnt3a sequence at 0.1 µg
Secondary IRDye 680 Conjugated Goat Anti-Rabbit IgG at 1/15000 dilution
Predicted band size : 39 kDa Observed band size : 39 kDa ab19925 detects a band of the expected size for recombinant mouse Wnt3a.
