High-affinity folate binding in human prostate.
Binding of 3H-folate in Triton X-100 solubilized human prostate homogenate was of a high-affinity type and displayed apparent positive cooperativity typical of specific folate binding. Radioligand dissociation was slow at pH 7.4, but rapid at pH 3.5. Gel chromatography revealed two major folate binding proteins (M(r) approximately 100 and 25 kDa), but only one single band (M(r) approximately 65...
متن کاملManganese and Iron Binding to Human Transferrin
The characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. Both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (Mn-tf) and 465 nm for iron-transferrin (Fe-tf). Addition of manganese (1.5 µg/ml) to the reaction mixture contai...

متن کاملA high-affinity folate binding protein in human semen.
The presence of a folate binding protein of high-affinity type (affinity constant 3.10(10) M-1, maximum folate binding 1.4 nM) in human semen was demonstrated in equilibrium dialysis experiments (37 degrees C, pH 7.4) with the radioligand 3H-folate. Radioligand dissociation from the binding protein was slow at pH 7.4, but rapid at pH 3.5. By use of rabbit antibodies against 25 kDa human milk fo...
متن کاملCharacteristics of high-affinity folate binding in human leukocytes.
High-affinity binding of [3H]folate in leukocytes from normal subjects was studied in equilibrium dialysis experiments (pH 7.4, 37 degrees C). Binding displayed positive cooperativity, and the binding affinity increased with decreasing concentration of the binding protein. Both phenomena could be interpreted in terms of ligand binding to a polymerizing system where the affinity of ligand for th...
