Prostate-specific antigen in serum occurs predominantly in complex with a1-antichymotrypsin. Clin Chem 1991;37:1618-25.
Serum prostate-specific antigen complexed to a1-antichymotrypsin as an indicator of prostate cancer.
Serum prostate specific antigen complexed to
a1-antichymotrypsin as an indicator of prostate cancer.
Prostate-specific antigen and its complexes with
a1-antichymotrypsin in the plasma of patients with prostatic disease.
A complex between prostate-specific antigen and a1-antichymotrypsin is the major form of prostate-specific antigen in serum of patients with prostatic cancer: assay of the complex improves clinical sensitivity for cancer.
In vitro stability of free prostate-specific antigen (PSA) and prostate-specific antigen (PSA) complexed to a1-antichymotrypsin in blood samples.
Rapid exponential elimination of free prostate-specific antigen contrasts the slow, capacity-limited elimination of PSA complexed to
a1-antichymotrypsin from serum.
a1-Antichymotrypsin production in PSA-producing cells is common in prostate cancer but rare in benign prostatic hyperplasia.
Amino acid sequence at the reactive site of human
a1-antichymotrypsin. J Biol Chem 1983;258:12749-52.
Immunodetectable PSA in serum is mainly bound with
a1-antichymotrypsin, whereas a minor fraction is free.
PSA, a serine protease, forms complexes with serine protease inhibitors such as [alpha]2-macroglobulin and
a1-antichymotrypsin (ACT) (2).
