Immunofluorescence is an important technique required to observe expression, localization and colocalization of proteins within the cell. Here we describe the immunofluorescence and subsequent confocal microscopy technique of tumor necrosis factor-α (TNF) in human neutrophils (polymorphonuclear leukocytes; PMN). The qualitative technique can be used to observe the expression pattern changes from resting to stimulated leukocytes. Colocalization with other cytokines, proteins, or organelles can be observed. This immunofluorescence technique can be done in 1–2 days.
