I tried this antibody at different dilutions. The only staining I observed was observed on the walls of blood vessels. This pattern was observed in all brain areas. The pictures shows the staining observed at the level of the thalamus.
The sections used came from animals perfused fixed with Paraformaldehyde 4% with 15% of a solution of saturated picric acid, in phosphate buffer 0.1M. Following postfixation in the same fixative overnight, the brains were cryoprotected in sucrose 30% overnight. Brains were then cut using a cryostat and the immunostainings were performed using the ‘free floating’ technique.
Thank you for your valuable feedback. Ab18523 is a Fast Track antibody and has not yet been fully characterized. it appears from your data that the antibody may not be suitable for IHC-FoFr under these experimental conditions. We hope this information is useful to our customers.
