Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Tau (phospho S396) antibody [EPR2731] - BSA and Azide free (AB156623)

This data was developed using ab109390, the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded human cerebral cortex tissue* labelling Tau (phospho S396) with ab109390 at 0.1ug/ml followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

Positive staining in human cerebral cortex.

The section was incubated with ab109390 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 a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Heat mediated antigen retrieval with sodium citrate buffer (pH 6.0 epitope retrieval solution1) for 20 mins.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Tau (phospho S396) antibody [EPR2731] - BSA and Azide free (AB156623)

IHC image of Tau (phospho S396) staining in human Alzheimer hippocampus formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with citrate buffer. The section was then incubated with unpurified ab109390 at 1/1000 dilution for 2 hoursat 21ºC. A biotin conjugated goat-anti-rabbit antibody was used as a secondary at 1/250. The section shows clear neurofibrillary tangles in a subset of neurons.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab109390).

Immunohistochemistry analysis of frozen rat cerebrum tissue sections labeling Tau (phospho S396) with ab109390 at 1/100 (1 μg/mL). ab150077 Alexa Fluor^®488 Goat anti-Rabbit at 1/1000 (2 μg/mL) was used as the secondary antibody. Sections were fixed with 4% PFA and permeabilised with 0.2% Triton X-100. DAPI (blue) was used as nuclear counterstain. Antigen retrieval was heat mediated using sodium citrate buffer (10mM citrate pH 6.0 + 0.05% Tween-20).

Cytoplasmic staining on rat cerebrum, the signal decreased after phosphatase treatment at 37℃ for 2h.

Immunohistochemical staining of paraffin embedded human glioblastoma with purified ab109390 at a dilution of 1/4000. A pre-diluted HRP polymer for rabbit/mouse IgG was used as the secondary antibody and the sample was counter-stained wirh hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

Immunohistochemistry analysis of paraffin-embedded human colon tissue sections labelling Tau (phospho S396) with ab109390 at 1/4000 dilution (0.026 μg/mL). The section was incubated with ab109390 for 30 mins at room temperature. Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) was used as the secondary antibody. Sections were counterstained with Hematoxylin. Antigen retrieval was heat mediated using Bond™ Epitope Retrieval Solution 2 (pH 9.0) for 20 minutes. Positive staining on ganglions of human colon without alkaline phosphatase treatment (image A); No signal was detected when tissues were treated with alkaline phosphatase (image B).The immunostaining was performed on a Leica Biosystems BOND® RX instrument.
