Comparison of the LFA-1 promoter-driven CD45.1 expression to wild-type CD45.2.
The staining antibodies are given on the vertical and horizontal axes (CD45.1, CD45.2, and LFA-1 [CD11a]). (A) All transgene-positive cells were isolated from mice on a CD45-null background. (B) Cells from transgenic mice were on a CD45.2+/− background.
