Cobalamin binding proteins in human seminal plasma.
Transcobalamin (TC) and haptocorrin (HC) are present in normal seminal plasma in substance concentrations ten- to twenty-fold that in blood. The results are given in range and (median). The substance concentration of seminal plasma TC is 3.6-21.9 (8.4) nmol l-1 and of seminal plasma HC 1.4-8.6 (3.0) nmol l-1. Compared to normals the substance concentration of TC is significantly lowered in post-vasectomy seminal plasma 2.2-2.9 (5.3) nmol l-1. The Stokes radius and the isoelectric points of seminal plasma TC are identical to TC in blood.
