製品詳細

Brand: BD Pharmingen™

Alternative Name: Cd18; ITGB2; Integrin β2 chain

Reactivity: Mouse (QC Testing)

Isotype: Rat IgG2a, κ

Immunogen: Mouse CTL glycoproteins

Application: Flow cytometry (Routinely Tested), Immunohistochemistry-formalin (antigen retrieval required), Immunohistochemistry-frozen (Tested During Development), Blocking, Immunoprecipitation, Stimulation, Western blot (Reported)

Concentration: 0.5 mg/ml

RRID: AB_396701

Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.

Regulatory Status: RUO

Preparation and Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The polyclonal antibody was purified from antiserum by negative adsorption and affinity chromatography.

推奨アッセイ手順

The alternative anti-CD18 mAb GAME-46 (Cat. No. 555280) is reported to block in vitro adhesion of LFA-1-expressing cells to the ligands ICAM-1, ICAM-2, and ICAM-3 and of Mac-1-expressing cells to ICAM-1, C3bi, and fibrinogen.

Product Notices

Since applications vary, each investigator should titrate the reagent to obtain optimal results.
An isotype control should be used at the same concentration as the antibody of interest.
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

M18/2

The M18/2 antibody specifically recognizes the common β2 chain of LFA-1 (CD11a/CD18, αLβ2 integrin), Mac-1 (CD11b/CD18, αMβ2 integrin), and gp150, 95 (CD11c/CD18, αXβ2 integrin). Expression of CD18 is limited to leukocytes, where it is widely distributed in consort with the three integrin α chains (CD11a, CD11b, and CD11c). Among splenocytes, NK cells have the highest density of CD18, and T lymphocytes express a higher density than the remaining cells. The β2 integrins are important mediators of leukocyte-endothelium interactions. It has been reported that M18/2 antibody blocks in vivo metastasis of the LB lymphoma to the spleen and that it blocks in vitro formation of aggregates of LB cells and splenocytes. However, other reports indicate that mAb M18/2 has no effect on CTL-mediated killing, adherence of C3bi-sensitized erythrocytes to Mac-1, antigen-specific binding of T cells to antigen-producing cells, or rejection of cardiac allografts. Recent in vitro studies indicate that M18/2 antibody stimulates adhesion of Mac-1 to its ligands C3bi and ICAM-1, and it stimulates adhesion of LFA-1 to ICAM-1, but it has no effect upon the interactions of LFA-1 with ICAM-2 nor ICAM-3.

Purified

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
