Native Human prostate specific Antigen

Native Human prostate specific antigen preparation is a purified form of human prostate-specific antigen (PSA), a glycoprotein of ~30 kDa found mainly in prostatic tissue and seminal fluid. PSA is also present in small quantities in the serum of normal men and is often elevated in the presence of prostate cancer and in other prostatic disorders.Native Human prostate specific antigen demonstrates high specific activity and low levels of any contaminating proteins, including those with trypsin-like protease activity (Manning et al. 2012).
