Figure 5: Immunogold electron microscopic analysis of BPI in mouse cauda epididymal spermatozoa. (a) Negative control using preimmune rabbit serum; no labeling was observed. (b) BPI-positive particles distributed throughout the acrosomal matrix. BPI: bactericidal/permeability-increasing protein. Bars = 1 μm.
