Expression of GATA2 in mature NK cells. B cells, T cells, monocytes, and NK cells (all 10⁶) or 5 × 10⁵ CD56^bright or CD56^dim NK cells were isolated from peripheral blood of a healthy donor by FACS, lysed, and immunoblotted for (A) GATA2 and (B) actin as a loading control. Shown is 1 of 3 representative experiments. B, CD19⁺ B cells; M, CD14⁺ monocytes; MW, molecular weight protein ladder; NK, CD56⁺CD3⁻ NK cells; T, CD3⁺ T cells.
