CD300a expression by neutrophils. (A) Expression of CD300a on freshly isolated human peripheral blood neutrophils (filled histogram). Empty histogram is background staining obtained with isotype control mAb. (B) Differentiated neutrophils obtained by treating HL-60 cells with 10-6 M RA for 4 days. The expression of CD300a, CD11b and CD14 in differentiated cells (continuous line) compared with non-differentiated cells (dotted line) is shown. These data are representative of 3 independent experiments.
