Related Product Information for Free PSA native protein
Description:
Purified human Free PSA protein.
Background:
Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), is a glycoprotein enzyme encoded in humans by the KLK3 gene. PSA is an androgen-regulated serine protease produced by both prostate epithelial cells and prostate cancer (PCa) and is the most commonly used serum marker for cancer. It is a member of the tissue kallikrein family, some of the members of which are also prostate specific. PSA is a major protein in semen, where its function is to cleave semenogelins in the seminal coagulum. PSA is secreted into prostatic ducts as an inactive 244-amino acid proenzyme (proPSA) that is activated by cleavage of seven N-terminal amino acids. Measurement of free versus total PSA can increase specificity for PCa. PSA is also widely used to monitor responses to therapy and is under investigation as a therapeutic target.

Product Notes
The Free PSA (Catalog #AAA355511) is a Native Protein produced from Human seminal fluid and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Free PSA can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA). Other applications have not been tested. Researchers should empirically determine the suitability of the Free PSA for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Free PSA, Native Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
