Procion red HE-3B extracts plasminogen from human serum

The selective retardation of NADP+-dependent dehydrogenases by immobilized procion red HE-3B.

The capacities of Procion Red HE-3B and Cibacron Blue F3G-A immobilized to Sepharose CL-4B and Matrex 201R for NAD+-, NADP+- and NAD(P)+-dependent dehydrogenases were measured. Procion Red HE-3B columns retarded NADP+-dependent dehydrogenases more effectively than NAD+-dependent dehydrogenases, whilst immobilized Cibacron Blue F3G-A retarded NAD+-dependent dehydrogenases more effectively than N...

Purification of hydrogenases by affinity chromatography on Procion Red-agarose.

The agarose-coupled triazine dye Procion Red HE-3B has been demonstrated to be applicable as an affinity gel for the purification of five diverse hydrogenases, namely the soluble, NAD-specific and the membrane-bound hydrogenase of Alcaligenes eutrophus, the membrane-bound hydrogenase of the N2-fixing Alcaligenes latus, the reversible H2-evolving and the unidirectional H2-oxidizing hydrogenase o...

RED CELLS Immunoassay for human serum hepcidin

We developed and validated the first serum enzyme-linked immunosorbent assay for hepcidin, the principal iron-regulatory hormone that has been very difficult to measure. In healthy volunteers, the 5% to 95% range of hepcidin concentrations was 29 to 254 ng/mL in men (n 65) and 17 to 286 ng/mL in women (n 49), with median concentrations 112 versus 65 (P < .001). The lower limit of detection was ...

The interaction of yeast hexokinase with Procion Green H-4G.

1. A number of reactive triazine dyes specifically and irreversibly inactive yeast hexokinase at pH 8.5 and 33 degrees C. Under these conditions, the enzyme is readily inactivated by 100 microM-Procion Green H-4G, Blue H-B, Turquoise H-7G and Turquoise H-A, is less readily inactivated by Procion Brown H-2G. Green HE-4BD, Red HE-3B and Yellow H-5G and is not inactivated at all by Procion Yellow ...
