We report a protocol for concomitant purification to homogeneity of both prostatic acid phosphatase [orthophosphoric-monoester phosphohydrolase (acid optimum), EC 3.1.3.2] and prostate-specific antigen, from human seminal fluid. The method requires only two chromatographic steps: passage through an Affigel-Blue column and gel filtration HPLC. This is a fast, efficient procedure for purification of these two important tumor markers, which are specific for prostatic cancer.
