AChE, ACEE, ACES_HUMAN, Acetylcholinesterase, ACHE, ARACHE, N-ACHE, VT, Acetylcholinesterase isoform E4-E6
Acetylcholinesterase (ACHE) belongs to the type-B carboxylesterase/lipase family. ACHE catalyzes the breakdown of acetylcholine and other choline esters that play a role as neurotransmitters. During neurotransmission, ACH is released from the presynaptic neuron into the synaptic cleft and binds ACH receptors on the post-synaptic membrane, transmitting the signal from the nerve. ACHE is located on the post-synaptic membrane, terminates the signal transmission by hydrolyzing ACH.
ACHE Human Recombinant produced in HEK cells is a single, glycosylated, polypeptide chain (32-614 a.a) containing a total of 592 amino acids, having a molecular mass of 65.6 kDa.
ACHE is fused to a 6 amino acid His-tag at C-terminus,and is purified by proprietary chromatographic techniques.
Sterile Filtered colorless solution.
The ACHE solution (0.25mg/ml) contains 10% Glycerol and Phosphate-Buffered Saline (pH 7.4).
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
Specific activity is > 6,000 nmol/min/ug. Defined by the amount of enzyme that cleaves 1 nmole of acetylthiocholine per minute at pH 7.5 at 25˚C.
