Dihydro-β-erythroidine hydrobromide
- CAS号:
29734-68-7
- 供应商:
上海莼试
- 保存条件:
Desiccate at RT
- 规格:
10mg 50mg
使用方法:
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。

产品描述:
分子式:C16H21NO3.HBr

Shipping Condition:Evaluation sample solution : ship with blue ice All other available size: ship with RT , or blue ice upon request
IC50: 1.3 μM for α2β2, 2.3 μM for α2β4, 0.41 μM for α3β2, 23.1 μM for α3β4, 0.37 μM for α4β2, and 0.19 μM for α4β4 [1]Dihydro-β-erythroidine hydrobromide (DHβE), the hydrogenated derivative of erythroidine, is a competitive antagonist of neuronal nicotinic acetyicholine receptors (or nAChRs). Nicotinic acetyicholine receptors are neuron receptor proteins which respond to the neurotransmitter acetylcholine.In vitro: DHβE has been shown to be a purely competitive antagonist of the neuronal nicotinic receptor [1].In vivo: DHβE is able to block some of the central actions of nicotine after systemic and intrathecal administration. The mechanism of blockade is different from that of mecamylamine, a classical ganglionic antagonist, and may involve a direct action of DHβE on nicotine receptor [2].Clinical trial: DHβE can be given orally and may cross the blood-brain barriers. At 200 mg/kg, the effects were bradycardia and visual difficulty most often described as blurring of vision or double vision; at 6 mg/kg, produced aforementioned effects plus hypotension and reduction in grip strength with accompanying feelings of sedation [3].
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。
