AChR (Acetylcholin receptor) protein


Proteins
Our AChr is directly purified from the acetylcholine receptor of Torpedo californica. It is the best example on how customized protein purification beads can be used to isolate a protein without any epitope tags. The protein was purified through agarose resin coupled to neurotoxin-3 from king cobras, a natural ligand of AChR.

Affinity tags none
Size (excluding additional elements) alpha 52,7 kDa;
beta 56,1 kDa;
gamma 58,1 kDa;
delta 60 kDa
Expression system T. Californica (native)
Purified via Protein-specific affinity matrix using immobilized agonist ligand, dialysis
Buffer 137 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4, 1.8 mM KH2PO4, 5 % glycerin; 0,1 % Triton
Purity (SDS-PAGE) >95 % as determined by SDS-PAGE
Activity Native AChR from T.Californica, purified as functional heterotetramer binding to Neurotoxin-3 ligand
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.
