CD11b (integrin alpha M subunit) is a type I transmembrane glycoprotein. CD11b combines with the Integrin beta 2 subunit (CD18) to form the non-covalent heterodimer Integrin alpha M/beta 2, also known as Mac-1 and complement receptor type 3 (CR3). The CD11b/CD18 (Mac-1) heterodimer has a theoretical molecular weight of 127kDa but is often observed near 170kDa due to post translational modifications. Integrins are transmembrane proteins that mediate interactions between adhesion molecules on adjacent cells and/or the extracellular matrix. Integrins have diverse roles in several biological processes, including cell migration during development, wound healing, cell differentiation, and apoptosis. The particular integrin CD11b is known as a pro-inflammatory molecule given its ability to promote phagocyte cytotoxic functions while enhancing several effector molecules such as FcGR, uPAR, and CD14 (1). In macrophages, CpG-DNA stimulates lysosomal degradation and vacuolar acidification, subsequently promoting CD11b release via TLR9 (2). During an acute infection, high CD11b/Mac-1 expression on antigen-specific CD8 (+) T cells can signify recent activation of the immune system, whereas naive T cells and virus-specific memory CD8 (+) T cells express little or no Mac-1 when exposed to a virus (3). Variations at the ITGAM gene, which encodes for the CD11b chain of the Mac-1 integrin, is one of the main genetic risk factors involved in systemic lupus erythematosus /SLE disorder (4).

Batazzi A. Elucidating the role of Keratin 17 in cervical carcinogenesis Thesis. 2014 (IHC-Fr)
Details: Integrin alpha M/CD11b antibody used in IHC-Fr application for the detection of macrophages and neutrophils on un-fixed cervical epithelium cryosections from WT, HPV16tg/+K17-/- and HPV16tg/+K17+/+ mice. The data showed that HPV16tg/+K17-/- mice have a higher number of intra-epithelial immune cells (Figure 14, page 39)
Cells were treated with LPA or LPA and an LPAR5 inhibitor in order to investigate the expression of iNOS after 24 hours. CD11b antibody was used in a dilution 1:100 in order to stain primary murine microglia.Cy2 (green) and Cy3 (red) were used as secondary antibodies.
FAQs for CD11b Antibody (NB600-1327). (Showing 1 - 8 of 8 FAQs).
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.
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.
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.
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.
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.
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.
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.
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
CD11b - More than a microglial marker The protein CD11b has been implicated in the various adhesion-related interactions of cells such as monocytes, macrophages, natural killer (NK) cells, and granulocytes. It is part of a heterodimer that consists of CD11b and CD18. It also modulates the... Read full blog post.
