Total PSA (human) ELISA kit Prostate-specific antigen (PSA), also known as γ-seminoprotein or kallikrein-3 (KLK3), is a kallikrein-like protease produced by the epithelial cells in the prostate gland, the lining of the urethra and the bulbourethral gland. The Total PSA ELISA kit, from Enzo Life Sciences, enables the detection of total PSA in human serum, plasma, urine and tissue culture media samples in just 2.5 h for up to 40 samples in duplicate. The assay provides an equal molar detection on different forms of PSA in human matrices, which is said to improve the accuracy and sensitivity of the measurement on the total PSA levels. It can detect as little as 0.287 pM (or 0.024 ng/mL), with negligible cross reactivity with similar proteins (KLK2, ACT). It provides fully quantitative results that are said to surpass semi-quantitative Western blot analysis. United Bioresearch Products Pty Ltd www.unitedbioresearch.com.au
Imaging system
