Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-GFAP (phospho S13) antibody [EPR25281-65] - BSA and Azide free (AB303561)

This data was developed using ab303560, the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded human cerebrum tissue labeling GFAP (phospho S13) with ab303560 at 1/500 dilution (1.016 µg/mL), followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining was observed on astrocyte in human cerebrum without alkaline phosphatase treatment (image A, PMID : 22528834). No signal was detected when tissues were treated with alkaline phosphatase (image B). The section was incubated with ab303560 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin. Secondary antibody only control : Secondary antibody is ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) at Ready to use dilution. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins was used.
