Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Iba1 antibody [EPR16588] - Microglia marker (AB178846)

IHC image of Iba1 staining in human normal hippocampus formalin fixed paraffin embedded tissue section performed on a Leica Bond™ 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 ab178846 at 1/2000 dilution 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.

Multiplex immunohistochemistry - Anti-Iba1 antibody [EPR16588] - Microglia marker (AB178846)

Chromogenic multiplex immunohistochemical staining of FFPE normal human cerebellum tissue. ab177487, anti-NeuN DAB chromogen. ab68428, anti-GFAP purple chromogen and ab178846, anti- Iba1 teal chromogen plus haematoxylin counterstain. Chromogenic immunostaining was performed on a Roche Ventana Discovery Ultra instrument. The section was deparaffinised and incubated with CC1 solution for 24min 100°C. Following this with 3 rounds of staining in the order of ab177487 (1/600), ab178846 (1/4000) ab68428 (1/1000). Between rounds of staining, antibody denaturation was conducted using Ultra CC2 solution for 8min at 100°C to avoid cross reactivity. Signal was developed with anti-rabbit HQ followed by anti-HQ HRP coupled with Chromomap DAB kit, Discovery purple or Discovery teal chromogens and haematoxylin II counterstain.

IHC-tissue clearing - Anti-Iba1 antibody [EPR16588] - Microglia marker (AB178846)

Anti-Iba1 ab178846 was used with Tissue clearing kit – CUBIC (ab316246) and 3D Tissue Staining Kit – CUBIC (ab316248) to penetrate stain and clear a whole mouse brain.

Learn more about tissue clearing kits reagents and protocols designed to make it easier to stain whole brains and get more data from each valuable tissue sample.

For a whole mouse brain we recommend starting with 3.5 ug of ab178846 and using a Fab fragment secondary antibody with 2.34 µg to create an antibody complex before 3D staining (see protocol for details). Additive A was used during the staining process.

The sample was imaged using a light-sheet microscope.

Western blot - Anti-Iba1 antibody [EPR16588] - Microglia marker (AB178846)

Abcam recommends blocking in milk for cleaner blots with reduced background, in comparison to BSA.

This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour before being incubated with ab178846 (anti-Iba1 antibody; 1/500 dilution) for 18 hours at 4°C. Antibody binding was detected using ab97040 (HRP-labelled goat anti-mouse IgG) at 1 : 50,000 dilution for 1 hour at room temperature and visualised using ECL development solution ab133406.

Blocking buffer and concentration : 5% NFDM/TBST. Diluting buffer and concentration : 5% NFDM/TBST. IBA1 is a relatively minor protein of brain and is much more abundant in spleen (PMID : 8912632, PMID : 29232670). We suggest loading higher amount of brain lysate or using lower dilution of antibody for detecting signal in brain related lysates. ab181602 was used as loading control.
