1.本蛋白酶抑制剂混合物为100×的储存液,使用时按照1:100的比例加入到裂解液中(例如,1ml裂解液中加入10μl蛋白酶抑制剂混合物),混匀后即可使用。根据需要,0.5M的EDTA也按照1:100的比例加入到裂解液中(如用于检测金属蛋白酶活性,则不宜添加EDTA)。含有蛋白酶抑制剂混合物的裂解液宜现用现配,不宜配制后冻存待后续使用。
2. 待所需的抑制剂添加完毕混匀后,就可以开始进行哺乳动物组织的裂解和蛋白提取。

Galantamine is a potent inhibitor of acetylcholinesterase (AChE) with IC50 value of 410 nM. [1]Acetylcholinesterase is a hydrolase. It belongs to carboxylesterase family of enzymes It hydrolyzes the neurotransmitter acetylcholine and has very high catalytic activity. AChE exits in many types of conducting tissue: nerve and muscle, motor and sensory fibers and central and peripheral tissues. AChE located on the post-synaptic membrane. It stops the signal transmission by hydrolyzing ACh. Ach plays an important role in neurotransmission. ACh is released into the synaptic cleft then binds to ACh receptors which located on the post-synaptic membrane. Inhibition the activity of AChE will result in impeded neurotransmission by leading to accumulation of ACh in the synaptic cleft. AChE also is an important target for Alzheimer disease.[1]Galantamine significantly decreased apoptotic effect induced by thapsigargin at 300 nM in SH-SY5Y cells. Galantamine can more significantly increase cell viability in LDH assays at 10 nM in neuroblastoma cells. Galantamine at 300 nM increase the cell viability treated with Aβ. Galantamine significantly increaseed the expression level of Bcl-2 by 3.1 fold at 300nM in chromaffin cells.[1]Galantamine can significantly incrase the mRNAs level of IGF2 at 3mg/kg in the mice hippoc ampus. Galantamine also transient decrease the BDNF mRNA levels and increase the FGF2 mRNA levels. Galantamine significantly increased the expression of IGF2 protein levels at 3 mg/kg in the hippocampus of mice.[2]
注意事项:
抗逆滴加序列
每次向板内滴加抗原时,移液器滴头要与平面45度悬空,不要触碰到孔内的液体,由后向前依次滴加(即浓度由低往高滴加)。
抗感染反应期
抗原抗体在室温20~25℃下,必须反应30min以上,若环境温度低于室温,可将微量反应板置于恒温培养箱中,使二者充分反应。
旅游温度
磷酸盐缓冲液的pH值要在高压灭菌后进行滴定,往往在高压后pH值会有所改变,所以高压后再调一次pH值更为准确。磷酸盐缓冲液一经使用保存期不要超过3周。当pH<5.8时,红细胞会产生自凝现象;当pH>7.8时,图形洗脱加快,易造成肉眼观察产生误差;p H=7.2时,红细胞沉降最充分,图形最清晰。
当滴注 1%红细胞悬液时,应经常摇晃红细胞悬液,使红细胞均匀地分布在磷酸缓冲液中,以防止红细胞下降。
反应时间及温度
加入鸡红血球之后,反应板在室温(20~25℃)静置30~40min,对照孔血球下沉于孔底,即可判定结果。若室温达不到实验要求,需相应调整反应时间。当环境温度低于4℃时,红细胞发生自凝;高于37℃时,会发生反应物分离和红细胞溶血。

局部用于治疗青光眼,能缩小瞳孔,降低眼内压,收缩睫状肌而引起调节痉挛等。常用0.005%溶液滴眼,作用较毛果芸香碱强而持久,但刺激性较大。又由于收缩睫状肌的作用较强,可引起头痛。滴眼后5分钟即出现缩瞳,眼内压下降作用可维持1~2天,调节痉挛现象消失较快。滴眼时应压迫内眦,避免药液流入鼻腔后吸收,引起中毒。 加兰他敏(galanthamine)也是可逆性抗胆碱酯酶药,体外抗胆碱酯酶效价约为毒扁豆碱的1/10。可用于重症肌无力,但疗效较差,也用于脊髓前角灰白质炎(小儿麻痹症)后遗症的治疗。
