Background

The Integrin alpha M subunit (CD11b), associates with the Integrin beta 2 subunit (CD18) to form the non-covalent heterodimeric Integrin CD11b/CD18, also known as Mac-1 and CR-3. Upon activation, CD11b/CD18 is expressed on granulocytes, monocytes, a subset of NK cells and activated lymphocytes. Integrin CD11b/CD18 functions as a receptor for complement fragment iC3b, ICAM-1 (CD54), ICAM-2 (CD102) and fibrinogen to mediate phagocyte adhesion, migration and ingestion of complement-opsonized particles (1‑3).

FAQs for CD11b Antibody (MAB11242). (Showing 1 - 8 of 8 FAQ).

  1. I am looking for a Mac-1 (microglia cell marker) antibody to do immunostaining with my mouse brain and I checked, you have a lot of antibodies for this biomarker. I don't know which one is the best to be used for immunohistology on mouse brain tissue. Could you please help with this?
    • I would recommend NB110-89474. This antibody has been published in 11 scientific articles, including several times in IHC in mouse. As long as CD11b is expressed in your sample, it should work just fine and is backed by our 100% Novus Guarantee.
  2. What types of cells can this CD11b antibody be used as a marker for?
    • A study used this CD11b antibody to stain granulocytes in mouse uterine tissue in IHC. CD11b is also expressed on other leukocytes such as monocytes, macrophages, and natural killer cells.
  3. Do you know if this CD11b antibody can be used in CD11b positive cell depletion? 
    • This particular CD11b antibody is not reccomended for depletion studies due to the preservative used; however, our CD11b antibody NBP1-06650 is offered in a preservative free format and has been validated for blocking.
  4. Looking for a bone marrow macrophage marker can you recommend a CD11b antibody for ICC?
    • I would recommend NB110-89474 which is our most popular CD11b antibody and has been validated in ICC and cited in 18 publications.
  5. We need a CD11b antibody for IHC-P on mouse tissue conjugated to FITC, do you have one that will work?
    • We have 3 CD11b antibodies for IHC-P and just one CD11 b antibody we offer conjugated to FITC, NB110-89474F.
  6. The protocol says to do enzymatic antigen retrieval before incubating with the CD11b antibody, which enzyme is used?
    • The protocol is referencting the PIER method using Proteinase K as the enzyme.
  7. I'm not sure if this will work for me, can I get a free sample of your CD11b antibody to test?
    • We don't offer free samples but we do offer this CD11b antibody in a trial size of 0.025 ml at a reduced cost, all antibodies are backed by our 100% guarantee to work in all validated species and applications on the product's web page.
  8. Is CD11b antibody also staining neutrophils in the brain
    • CD11b is typically used as a marker for granulocytes and macrophages. You may need a combination of markers to specifically identify neutrophils
