Acetylcholinesterase/ACHE Protein, Human (CHO, His)

Acetylcholinesterase (ACHE) protein is pivotal in neurotransmission, rapidly hydrolyzing acetylcholine in the synaptic cleft to terminate signal transduction at the neuromuscular junction. Beyond neurotransmitter regulation, ACHE is implicated in neuronal apoptosis, indicating a broader role in cellular processes associated with programmed cell death. Acetylcholinesterase/ACHE Protein, Human (CHO, His) is the recombinant human-derived Acetylcholinesterase/ACHE protein, expressed by CHO , with C-6*His labeled tag. The total length of Acetylcholinesterase/ACHE Protein, Human (CHO, His) is 583 a.a., with molecular weight of ~66 kDa.

Acetylcholinesterase (ACHE) protein plays a crucial role in neurotransmission by rapidly hydrolyzing the acetylcholine neurotransmitter in the synaptic cleft, thereby facilitating the termination of signal transduction at the neuromuscular junction. Beyond its essential function in neurotransmitter regulation, ACHE is implicated in neuronal apoptosis, suggesting a broader role in cellular processes related to programmed cell death.

Measured by its ability to cleave Acetylthiocholine. The specific activity is 308.73 nmol/min/μg, as measured under the described conditions.

• 
  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
