Flow cytometry was used to measure the modulation of neutrophil surface adhesion receptor expression using the following fluorochrome-conjugated anti-human antibodies: anti-CD18 FITC (mouse
IgGp clone 6.7, BD); anti-CD11b PE (mouse [IgG.sub.2a], clone D12, BD); anti-CD62L FITC (L-selectin, mouse [IgG.sub.1], clone DREG56, Beckman Coulter); and anti-CD45 APC-H7 (mouse [IgG.sub.1], clone 2D1, BD).
