A. Western blot for OLFM4 from the bone marrow of wild type, heterozygous and OLFM4 null mouse. B. Flow cytometric dot plots of CD11b+ bone marrow cells from wild type BALB/c, heterozygous, and OLFM4 null mouse, crossed onto BALB/c background for 5 generations, showing the loss of OLFM4 in null mice and confirming specificity of the antibody. C. Bar graphs showing there is no difference in the number of neutrophils in terms of percentage or number of neutrophils per femur when comparing OLFM4 null mice with wild type mice.
