Prostein, also known as P501S, is expressed in the vast majority of normal and malignant prostatic tissues. Prostein is localized in the Golgi complex and has a perinuclear-like cytoplasmic staining pattern. Prostein is a prostate-specific marker and has not been detected in any other normal or malignant tissues.

Moderate to strong granular cytoplasmic reactivity for prostein is seen in this example of prostate adenocarcinoma.

No staining for prostein is seen in the epithelium or stroma of the bladder.
