A polyclonal monospecific immune serum was raised against androgen-regulated proteins with Mr 24000 secreted by the mouse caput epididymidis. Sections of frozen tissues from the different regions of the epididymis have been studied by indirect immuno- fluorescence. Results indicate that the antigens are secretory proteins produced by the epithelial cells of the caput epididymidis, essentially in the medial and distal segments. Accumulation of the antigens was observed in the lumen of the caput and the corpus epididymal duct. Subsequently, their association with the sperm surface occurred and persisted down to the cauda epididymidis.
