Amylin is a 37-amino acid peptide co-secreted with insulin from pancreatic β-ells. The plasma concentration of amyline increases with nutrient stimuli. AC187 is a potent amylin antagonist
In vitro: AC187 potently competes for rat amylin binding at high affinity sites such as rat nucleus accumbens membranes which have been useful in developing a number of selective ligands, including AC187. The Kd for amylin at this site is 28 pM, and the Ki for AC187 is 79 pM. AC187 is relatively selective in competing for amylin binding, displacing amylin from nucleus accumbens membranes with over 400-fold greater potency [1].
In vivo: AC187 was able to inhibit metabolic responses to exogenous amylin in the intact animal. An infusion of AC187 that was itself without effect on lactate levels in anesthetized rats, inhibited by more than 90% the lactate increment evoked by infusions of rat amylin. Other experiments have shown that AC187-induced amylin blockade action is surmountable by higher doses of amylin, indicative of a competitive antagonism [1].
Clinical trial: Up to now, AC187 is still in the preclinical development stage.

酶标仪选择重复性好的，线性范围宽的，故障率底的，售后服务跟的上的厂家的仪器就好了。
想请教一下各位大神，为什么我做的Caco-2细胞的药物干预，用酶标仪检测CCK8,5/6孔总是异常，按理说，药物干预后，数据应该是递增或递减的，然而234孔递减，5/6孔却上升了，7、8孔又是递减。请问有人有遇到过这种情况吗？？在此先谢谢各位亲了~

各位前辈，MTT法加样后第一天阳性组镜下看细胞全死了，样品组和阴性组镜下状态还可以，加DMSO后样品孔和阴性孔颜色粉红，阳性孔红紫到发黑，酶标仪检测，样品组和阴性组大概0.2-0.4，阳性组却有1.2-1.4，请问，这是怎么回事？细胞接板密度为4*104,100μL。向各位求助了，万分感谢！
测器和微处理器控制系统等组成.
光源灯发出的光线经过滤光片或单色器后,成为一束单色光.该单色光束经过酶标板中的待测标本,被标本吸收掉一部分后,到达光电检测器.光电检测器将投照到
上面的光信号的强弱转变成电信号的大小.此电信号经前置放大、对数放大、模数转换等处理后,送人微处理器进行数据处理和计算,最后通过显示器和打印机输出

请问BAC蛋白浓度测定波长是562，我们这边酶标仪的滤光片波长最接近的是595，这样也可以测吗
酶标仪有单波长和双波长检测功能有时使用者不知在什么情况下使用单或双波长检测。所谓的“单波长”就是使用一种对显色具最大吸收的波长即450 nm或492 nm进行比色测定；而“双波长”则除了用对显色具最大吸收的波长即450 nm或492 nm进行比色测定外，同时用对特异显色不敏感的波长如630 nm进行测定，酶标仪最后打印出来的吸光度则为二者之差。630 nm波长下得到的吸光度是非特异的，来自于板子上诸如指纹、灰尘、脏物等所致的吸收。因此，在ELISA比色测定中，最好使用双波长，且不必设空白孔。
