Applications | According to the number of visible implanted embryos on day 8 of pregnancy, it was shown that AEBSF inhibited embryo implantation in rat. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

AEBSF is a broad spectrum, irreversible inhibitor of serine proteases [1].
AEBSF is a covalently binding inhibitor of proteases, including trypsin, chymotrypsin, plasmin and thrombin. AEBSF was found to inhibit Aβ production in various cell lines. In K293 cells transfected with APP695 (K695sw), AEBSF showed does-dependent reduction of Aβ with IC50 value of about 1mM. In HS695 and SKN695 cells transfected with wild-type APP695, AEBSF showed inhibition effect with IC50 value of about 300 μM. AEBSF was also found to increase α-cleavege and inhibit β- cleavage. Besides that, as a protease inhibitor, AEBSF was reported to prevent monocyte-derived macrophages from lysing the leukemic cells. Incubation of macrophages with 150 μM AEBSF for 6 hours resulted in nearly maximum inhibition [1, 2].

1.模板提取（一般为RNA）：Trizol、氯仿、异丙醇、无水乙醇、DEPC处理水
2.模板浓度测定：分光光度计或NanoDrop
3.逆转录：逆转录试剂盒（或者一步法试剂盒），这一步可以用普通PCR做，也可以用水域做。
4.荧光定量PCR试剂：通常有用SYBR Green Mix做的，但是这里建议你用EvaGreen做，灵敏度和平行性都要好于SYBR Green，并且如果你那是ABI或者Stratagene的PCR如果用SYBR Green还需要加一步Rox很麻烦。
5.其他：除了以上的那些还需要离心管、PCR管或板（Axygen反应比较好）、移液枪等，暂时就想到这么多。
试剂盒在全球市场上的研发与销售呈快速上升趋势,2005年全球市场销售额超过200亿美元,且以15%左右的速度逐年增长.一方面是试剂盒的迅猛发展,而另一方面试剂盒市场良莠不齐的现象愈加明显,试剂盒的生产、销售及认证认可体制尚不完善,没有相应的标准或质量评价政策.且其灵敏度,稳定性及假阴/阳性控制尚不能满足检测需要,采用试剂盒进行检测的公信度受到质疑.
同时,食品安全领域是当前问题最多、最受关注的领域,这个领域的检测包括了物理、化学、微生物及分子生物学基础理论,无论是按检测原理、用途还是其它分类方式,涉及食品安全检测项目的试剂盒的品种是最全最多的.因此,从该领域着手从事评价制度的研究,便于获得基础性数据结果,并由此推广至动植物检疫及其它领域.
随着H7N9禽流感疫情的不断发散,国家流感中心已经多次发放人感染H7N9禽流感检测试剂,覆盖了全国31个流感网络实验室,并表示,诊断试剂的广泛发放是实现关口前移,控制疫情传播、蔓延的重要手段.而一旦H7N9监测关口继续前移,主动监测范围扩大,病毒检测试剂的需求量将进一步加大.
可采用H7N9亚型禽流感病毒RNA检测试剂盒（荧光PCR法）和H7N9禽流感病毒核酸检测试剂盒（PCR-荧光探针法）,定价分别为48人份/盒和48反应/盒,相比市场此前预期的100-200元之间的价格定位低了很多.在检验方法上,卫纪委提醒,前者需要配备全自动荧光PCR检测仪专用PCR扩增管和核酸分离试剂盒(硅胶膜吸附法)等必须设备及咽拭子样本,后者卫计委推荐采用达安基因生产的核酸提取试剂盒进行检验.
1、如果是提取的总蛋白，然后做WB，用β-actin或者GAPDH做内参肯定是没有问题的，这是公认的东西。
2、如果用膜蛋白提取试剂盒提取蛋白，再用β-actin作为内参似乎不妥，因为理论上来讲β-actin在膜上是不表达的。WB能做出β-actin来是因为膜蛋白提取时把胞质蛋白也提出来了。然而，如果我们试验目的是用药物处理细胞，比较处理前后某种膜蛋白的表达情况，此时用膜蛋白提取试剂盒提取膜蛋白后再用β-actin做内参似乎就不妥了，因为你根本不知道药物处理前后混杂了多少的胞质蛋白进来。如果没有胞质蛋白混进去的话，β-actin就是检测不到的。
3.逆转录：逆转录试剂盒（或者一步法试剂盒），这一步可以用普通PCR做，也可以用水域做。
4.荧光定量PCR试剂：通常有用SYBR Green Mix做的，但是这里建议你用EvaGreen做，灵敏度和平行性都要好于SYBR Green，并且如果你那是ABI或者Stratagene的PCR如果用SYBR Green还需要加一步Rox很麻烦。
5.其他：除了以上的那些还需要离心管、PCR管或板（Axygen反应比较好）、移液枪等，暂时就想到这么多。
