Slides were washed with 1x PBS and then blocked in 5% goat serum containing 0.3% Triton X-100. Iba-1 was stained using ab178847 at 1/500 dilution in immunohistochemical analysis. Representative immunofluorescence is depicted for KO Sham (F top left), KO injured (F bottom left), WT Sham (F top right), and WT injured (F bottom right) in the right and left hemispheres (blue = DAPI, green = Iba-1). Scale bars = 100μm, 20x. HI = hypoxic-ischemic brain injury.

Area occupied by Iba-1-positive staining was elevated in KO injured animals when compared to uninjured controls, while stain area was not elevated in WT injured animals

Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is ab97051 at 1/500 dilution.

Iba1 antibody ab178847 was used with Tissue Clearing Kit ab243298 to penetrate, stain and clear a 1 mm coronal section of mouse brain. Blue: DAPI , Green: Iba1.

Learn more about tissue clearing kits, reagents, and protocols designed to make it easier to stain thick tissue sections and get more data from each valuable tissue section.

For 1 mm brain sections, we recommend a starting dilution of 1:100, and also using Goat Anti-Rabbit IgG H&L AlexaFluor488 (ab150077) at a dilution of 1:400.
