P-30 is secreted by :
Answer: A
P-30 is secreted by the prostate gland (printed 'Prostrate').
P30 is the forensic name for prostate-specific antigen (PSA), a glycoprotein of molecular weight about 30 kDa produced by the epithelial cells of the prostate and found in high concentration in seminal fluid. Because it is present whether or not the man has sperm, testing for P30 (by immunodiffusion or rapid immunochromatographic cards) is used to confirm semen in sexual assault cases involving vasectomised or azoospermic men.
Salivary and parotid glands produce amylase, the marker for saliva, and the pancreas produces digestive enzymes and hormones. None of them produces P30.
