The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 56 kDa (predicted molecular weight: 56 kDa).
Use at an assay dependent concentration.
Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Does metabolize octanal and decanal but does not metabolize citral, benzaldehyde, acetaldehyde and propanal efficiently.
IHC image of ab75674 staining in human testis formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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 ab75674, 1µg/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.
Immunohistochemistry (Frozen sections) - Anti-ALDH1A2 antibody (ab75674)This image is courtesy of an anonymous abreview.
ab75674 staining ALDH1A2 on E9.5 mouse embryo sections by immunohistochemistry. The tissue was paraformaldehyde fixed and permeabilized in PBST prior to blocking in NOVOCASTRA protein block for 30 minutes at 25°C. The primary antibody was diluted 1/500 and incubated with the sample for 48 hour at 4°C. An Alexa Fluor 555 conjugated donkey anti-rabbit antibody, diluted 1/1000, was used as the secondary. Nuclear staining shown with DAPI.
