Technical Data
Acetylcholinesterase (ACHE, AChE)
Acetylcholinesterase (AChE, EC. is an enzyme located in the postsynaptic membrane and in the muscle endplates, where it hydrolyses the neurotransmitter acetylcholin. AChE from brain is a tetramer (G4-AChE) with a molecular mass of 320kD, AChE from erythrocytes is a dimer (G2-AChE) with a molecular mass of 170kD. Detection of higher levels of AChE in amniotic fluid can indicate fetal malformations such as neural tube defects.

Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:2000
Western Blot: 1-3ug/ml, observed in human brain (cerebellum) lysates on ~70kD bands
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
