Previously we reported that the 55-kDa fertility-associated protein in Holstein bull seminal plasma (SP) is osteopontin (OPN). The objective of the present study was to localize OPN in tissues and fluids in the Holstein bull reproductive tract to determine its origin. Antisera generated against human recombinant OPN, as well as antiserum prepared against purified bovine seminal plasma OPN, reacted with protein in SP, accessory sex gland fluid, seminal vesicle fluid, ampullary fluid, and urine… CONTINUE READING
