Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Iba1 antibody - Microglia marker (AB5076)
Immunohistochemical analysis of formalin-fixed, paraffin-embedded human lateral prefrontal cortex tissue labeling iba1 labeled microglia (labeled with black arrows) within the cortex using ab5076 at 1/1000 dilution. (Cropped image).
Sections were rinsed in 0.01 m PBS, pH 7.4, followed by 10% serum matching the species of the secondary antibody, 5% bovine serum albumin, and 0.1% Triton X-100 in 0.01 m PBS blocking solution for 1 h and incubated for 2 days at 4 °C in primary antibody. The sections were rinsed in PBS and incubated overnight at 4 °C with a horse anti-Goat IgG (Biotinylated) secondary antibody.

Iba1 (Ionized calcium-binding adapter molecule 1; allograft inflammatory factor 1, AIF1) is a prominent microglial marker extensively used in neuroscience research. Its expression increases in various neurodegenerative conditions, including Alzheimer's disease (AD), indicating microglial activation and neuroinflammation. Researchers utilize Iba1 in stainings to assess microglial response and activity in different models, making it essential for understanding inflammatory processes in the brain. Changes in Iba1 expression provide valuable insights into neuroinflammation, highlighting its importance in studying diseases like AD.
The Iba1 antibody (ab5076) is commonly used as a marker of microglia activation in staining and immunohistochemistry, given that ionized calcium binding adaptor molecule 1 (Iba1) is a microglia/macrophage-specific calcium-binding protein with actin-bundling activity that participates in membrane ruffling and phagocytosis in activated microglia.

Biological function summary
The involvement of Iba1 in actin polymerization impacts microglia's ability to perform phagocytosis and cytokine production. Iba1 does not appear to be part of any large protein complex but interacts directly with actin filaments to facilitate cytoskeletal reorganization. This function enables the cells to move and respond efficiently to tissue damage or pathogens in the CNS. It plays an important role in supporting cellular changes associated with immune surveillance and neuroinflammatory responses.
Pathways
Microglial activation relies heavily on Iba1 for executing acts linked with neuroinflammation. Iba1 engages in the NF-kB signaling pathway significant in managing inflammatory responses. It interacts with proteins such as MyD88 and IRAK4 which aid in transmitting signals from toll-like receptors. These pathways enable changes in gene expression critical for microglial response to various stimuli. Furthermore Iba1 also contributes to the PI3K/Akt pathway where it influences cell survival and proliferation interacting with proteins like Akt1 and PTEN.
