Product Overview
| Description | Prostatic acid phosphatase (PAP), also prostatic specific acid phosphatase (PSAP), is an enzyme produced by the prostate. It may be found in increased amounts in men who have prostate cancer or other diseases. The highest levels of acid phosphatase are found in metastasized prostate cancer. Diseases of the bone, such as Paget’s disease or hyperparathyroidism, diseases of blood cells, such as sickle-cell disease or multiple myeloma or lysosomal storage diseases, such as Gaucher’s disease, will show moderately increased levels. Certain medications can cause temporary increases or decreases in acid phosphatase levels. Manipulation of the prostate gland through massage, biopsy or rectal exam before a test may increase the level. PSAP was used to monitor and assess progression of prostate cancer until the introduction of prostate specific antigen (PSA), which has now largely displaced it. Recent work, suggesting it has a role in prognosticating intermediate and high-risk prostate cancer, has lead to renewed interest in this marker.[1] PSAP immunohistochemical staining is often used with PSA (staining), by pathologists, to help distinguish poorly differentiated carcinomas. For example, poorly differentiated prostate adenocarcinoma (prostate cancer) and urothelial carcinoma (bladder cancer) may appear similar under the microscope, but PSAP and PSA staining can help differentiate them;[2] prostate adenocarcinoma often stains with PSA and/or PSAP, while urothelial carcinoma does not. Prostatic acid phosphatase is present in semen and its presence can be used as a presumptive test for semen. Other acid phosphatases are present in other bodily fluids, but the high concentration of PAP in semen gives a strong indication that semen is present. PAP may play an important role in the transmission of HIV. Researchers at the University of Ulm in Germany found that PAP forms fibers made of amyloid. They called the fibers Semen-derived Enhancer of Virus Infection (SEVI) and showed that they capture HIV virions promoting their attachment to target cells. The association of PAP with HIV may increase the ability of the virus to infect human cells by several orders of magnitude. PAP may be a future target of efforts to combat the spread of HIV infection.[3] Source: Human Seminal Fluid Molecular Weight: ~100kD Storage and Stability: Lyophilized powder may be stored at 4°C.
