  • Synonym
    Acylcholine acylhydrolase; BCHE; Butyrylcholine esterase; Butyrylcholinesterase; CHE1; CHE1cholinesterase; Choline esterase II; cholinesterase 1; E1; EC 3.1.1.8; Pseudocholinesterase
  • Source
    Human BCHE, His Tag (BHE-H52H3) is expressed from human 293 cells (HEK293). It contains AA Glu 29 - Leu 602 (Accession # P06276-1).
    Predicted N-terminus: Glu 29
  • Molecular Characterization
    Online(Glu 29 - Leu 602) P06276-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 67.0 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH8.0. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

SDS-PAGE
Human BCHE, His Tag (Cat. No. BHE-H52H3) SDS-PAGE gel

Human BCHE, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

Bioactivity

Measured by its ability to cleave Butyrylthiocholine.The specific activity is >12,0000 pmol/min/μg, as measured under the described conditions (QC tested).

  • Background
    BCHE (also known as Butyrylcholinesterase, pseudocholinesterase, plasma cholinesterase, or BuChE) is a nonspecific cholinesterase enzyme that hydrolyzes many different choline esters. Both acetylcholinesterase and butyrylcholinesterase represent therapeutic targets for ameliorating the cholinergic deficit considered to be responsible for the declines in cognitive, behavioral and global functioning characteristic of Alzheimer's disease (AD).
