IHC-Fr image of human blood vessels stained with Ab86491 (1:250). The fixed brain sections were permeabilized using 0.1% PBS-Triton X for 1h. 10% donkey serum was used for 1 hour at 24°C to block protein-protein interactions.  The sections were then incubated with Ab8649 used at 1/250 dilution, overnight at +4°C. The secondary antibody was Alexa Fluor® 568 donkey anti-rat used at 1/1000 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.See Abreview
