Purity:Purified by Protein G affinity chromatography.
Form:Purified IgG conjugated to R. Phycoerythr(RPE) - lyophilized with 0.09% sodium azide, 1% BSA. Reconstitute with 1ml sterile ddH2O.
Specificity:Recognizes an epitope on the human CD18 molecule that is hidden in the CD11/CD18 heterodimer on resting cells. Clone 3H1050 (MEM-148) binds very weakly to resting peripheral blood leukocytes and strongly to all leukocytes upon cellular activation. The epitope recognized is also exposed during dissociation of the CD11/CD18 by low pH.
