CD18 is a 95 kD protein, also known as integrin β2 subunit. It is expressed on all leukocytes. CD18, in association with integrin α chain CD11a, CD11b, and CD11c forms LFA-1, Mac-1, and αXβ2, respectively, and plays an important role in leukocytes adhesion. The CD18 integrin complexes bind ICAM-1 (CD54), ICAM-2 (CD102), ICAM-3 (CD50), iC3b, and fibrinogen. The M18/2 antibody is able to block tumor cell metastasis and enhance cell adhesion.

FC - Quality tested
IP, WB, Block, Stim, IHC - Reported in the literature, not verified in house - Recommended Usage
-
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
Additional reported applications (for the relevant formats) include: immunoprecipitation1,2, Western blotting1, in vitro and in vivo blocking of tumor cells metastasis or stimulation of cell-adhesion2-6, and immunohistochemical staining7 of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections. The Ultra-LEAF™ purified antibody (Endotoxin <0.01 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 101417-101422).

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
