Web21 de abr. de 2014 · High efficiency acetylcholinesterase immobilization on DNA aptamer modified surfaces We report here the in vitro selection of DNA aptamers for electric eel acetylcholinesterase (AChE). One selected aptamer sequence (R15/19) has a high affinity towards the enzyme (Kd=157±42 pM). WebThis phosphorylationinhibits the binding of the acetyl group of the acetylcholine to the esteratic site of the cholinesterase. Because the acetyl group can't bind the cholinesterase, the acetylcholine can't be cleaved. …
