Western blot - Anti-Iba1 antibody - Microglia marker (AB153696)
BLOCKED IN 3% MILK. For ab153696 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 ab153696 (anti-Iba1 antibody; 1/500 dilution) for 18 hours at 4°C. Antibody binding was detected using HRP-labelled anti-Rabbit IgG for 1 hour at room temperature and visualised using ECL development solution ab133406.

CSF1R inhibition reduces microglial accumulation induced by SCI.a Schematics of experimental design showing the timeline of microglia depletion, spinal cord crush injury, and sacrifice. b Western blot analysis of spinal cord homogenates from sham-operated, injured with control or PLX3397-treated mice (n = 4 per group) for steady state levels of the microglia marker Iba1. c Quantification of b showing a robust increase in levels of Iba1 expression at 7 days following SCI. CSF1R inhibition reverses the increase induced by SCI. d–f Representative immunofluorescence images of mouse spinal cord sections showing Iba1+ microglia. The changes in number of Iba1+ microglia consist with the changes of Iba1 expression levels. Data are expressed as mean ± SD. Scale bars : e, f in f 100 µm.

Biological function summary
Iba1 modulates actin bundling facilitating changes in microglial morphology and motility. It does not form part of a multiprotein complex but is significantly involved in cytoskeletal dynamics. This protein's expression increases during brain injury indicating its role in response to neural trauma. Iba1 has calcium-binding properties which suggest that it might interact with proteins involved in calcium signaling pathways.
Pathways
Calcium signaling and actin cytoskeletal rearrangement are significant biological processes that involve Iba1. Within these pathways Iba1 interacts closely with other actin-binding proteins that affect microglial movement and morphology. Such interactions illustrate how Iba1 helps microglia navigate and respond to changes within the brain environment.
