Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Lead Time

3-7 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

The cDNA sequence encoding the extracellular domain (21-255AA) of human acetylcholine receptor subunit alpha (CHRNA1) was fused with an N-terminal 6xHis-Trx-tag and then expressed in E.coli. The product, recombinant fusion protein, was measured the purity of over 90% using SDS-PAGE. The gel showed an about 75-85 kDa molecular mass band of this protein under reducing conditions. This recombinant CHRNA1 protein may be used in the specific antibody synthesis or the studies of the neuroscience research area. In-stock recombinant CHRNA1 protein is offered now.

Target Background

Function

After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.

Gene References into Functions

In our analysis, we found one pair of SNPs in CHRNA1 and CHRNA7, plus one pair of SNPs in CHRNA2 and CHRNA3 reached corrected significance in tests for GxG interaction. Our study suggested evidence of interactions between CHRNs in controlling the risk of NSCL/P. PMID: 29688589
This study shown that the genetic analysis revealed that the very early onset JMG had a more prominent genetic predisposition in an autoantigen gene (CHRNA1). PMID: 28364296
Data suggest that the mutations made the cholinergic receptor nicotinic alpha 1 subunit channel (CHRNA1) resistant to the antagonists, not by impairing antagonist binding, but rather by producing a gain-of-function phenotype, e.g. increased agonist sensitivity. PMID: 27649498
