Description

Rat Monoclonal Antibody

The M18/2 antibody specifically recognizes the common β 2 chain of LFA-1 (CD11a/CD18, α Lβ 2 integrin), Mac-1 (CD11b/CD18, α Mβ 2 integrin), and gp150, 95 (CD11c/CD18, α Xβ 2 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 β 2 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 blocksi in vitro formation of aggregates of LB cells and splenocytes. However, other reports indicate that mAb M18/2 has no effect on CTLmediated 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.

The antibody was conjugated to BD Horizon™ BV786 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405nm and an acceptor dye with an Em Max at 786nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60nm filter). BV786 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 786 nm. BV786 offers a bright choice for the 6th detector off the violet laser.
