Monoclonal Antibodies That Recognize Various Folding States of Pure Human Butyrylcholinesterase Can Immunopurify Butyrylcholinesterase from Human Plasma Stored at Elevated Temperatures

Human plasma to be analyzed for exposure to cholinesterase inhibitors is stored at 4 °C or lower to prevent denaturation of human butyrylcholinesterase (HuBChE), the biomarker of exposure. Currently published protocols immunopurify HuBChE using antibodies that bind native HuBChE before analysis by mass spectrometry. It is anticipated that the plasma collected from human casualties may be stored...

Monoclonal antibodies to human butyrylcholinesterase reactive with butyrylcholinesterase in animal plasma.

Five mouse anti-human butyrylcholinesterase (BChE) monoclonal antibodies bind tightly to native human BChE with nanomolar dissociation constants. Pairing analysis in the Octet system identified the monoclonal antibodies that bind to overlapping and independent epitopes on human BChE. The nucleotide and amino acid sequences of 4 monoclonal antibodies are deposited in GenBank. Our goal was to det...

Human butyrylcholinesterase polymorphism: Molecular modeling.

BACKGROUND Prolonged apnoea following injection of ester-containing myoralaxants was first described in 1953. Because a large part of administered succinylcholine is shortly hydrolyzed by plasma butyrylcholinesterase (BChE) under normal conditions, prolonged apnoea was attributed to deficiency in BChE. It was found that BChE deficiency was due to genetic variations. Human BChE gene shows a larg...

Delipidation of Plasma Has Minimal Effects on Human Butyrylcholinesterase

Human butyrylcholinesterase (BChE) is purified in large quantities from Cohn fraction IV-4 to use for protection against the toxicity of chemical warfare agents. Small scale preliminary experiments use outdated plasma from the American Red Cross as the starting material for purifying BChE (P06276). Many of the volunteer donor plasma samples are turbid with fat, the donor having eaten fatty food...

Probing the Peripheral Site of Human Butyrylcholinesterase

Acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) catalyze the hydrolysis of the neurotransmitter acetylcholine and, thereby, function as coregulators of cholinergic neurotransmission. For both enzymes, hydrolysis takes place near the bottom of a 20 Å deep active site gorge. A number of amino acid residues within the gorge have been identified as important in facilitating efficient ...
