SC-57461A is a selective inhibitor of human recombinant LTB4 with IC50 value of 49 nM [1].LTB4 (leukotriene B (4)) is a leukotriene and plays an important role in inflammation. LTB4 functions through interacting with the specific cell-surface receptors BLTR1 and BLTR2 [2].SC-57461A is a potent LTB4 inhibitor and has a more potent activity than the reported LTA4 inhibitor RP64966. When tested with PMN cells, administration of SC-57461A significantly inhibited the synthesis of LT that induced by fMLP and PAF by acting on LTB4-BLTR1 interaction [3].In fasted CD rat model of calcium ionophore A23187-induced eicosanoid production, oral administration of SC-57461A showed effective inhibition on LTB4 with ED50 value of 0.3-1.0 mg/kg. When tested with AA-induced edema on the ear, oral administration of SC-57461A resulted in markedly inhibition of edema at doses of 0.8, 4 and 20 mg/kg [1].It is also been reported that SC-57461A inhibited LTB4A with Ki values of 23 nM and 27 nM for epoxide hydrolase and aminopeptidase, respectively [1].References: [1].

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
测试结果.
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。
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。
2、检测模式:荧光强度检测(FI), 荧光偏振检测(FP), 时间分辨荧光检测(TRF), TR-FRET, 高性能发光检测, 紫外/可见吸收光, AlphaScreen / AlphaLISA。
3、兼容 Take3™ 微量检测板 可进行体积为2 μL 的微量样品的检测
4、四光栅系统及带宽可调: Synergy H4 的光路整合了两个双光栅单色器. 这种四光栅设计. 可变的带宽设计极大的增加了检测的灵活性。
5、深度阻挡滤光片和二向色镜: Synergy H4的滤光片/二向色镜组合为,荧光强度、时间分辨荧光、荧光偏振及AlphaScreen / AlphaLISA 均具有最好的检测性能.向左转|向右转
我需要做pcr,做之前用酶标仪测定同一管dna浓度时,数字相差很大,有100度的也有五六十的,这是正常现象么,因为要做正交实验,需要准确的浓度,这种状况,我应该怎么确定浓度呢?求助求助!!
在双报告基因系统中,通常一个报告基因用于检测特定实验条件下待测物的反应,即“实验”reporter,另一个报告基因用来检测实验条件,类似于内部对照,用于校准“实验”reporter的数据。通过这种方法,可减少内在的变化因素所削弱的实验准确性,例如:转染效率、细胞活性、细胞裂解差异以及加样操作过程中引起的差异。Promega公司的Dual-Luciferase系统利用萤火虫和海肾荧光素酶的活性分别检测实验组和对照组。萤火虫荧光素酶是一种分子量为61KD的单体酶,分两步催化虫荧光素的氧化反应,产生560nm的光,海肾荧光素酶是一种分子量为36KD的单体酶,催化海肾荧光素的氧化反应,产生中心波长为480nm的蓝光。萤火虫荧光素酶和海肾荧光素酶没有种源同源性,对应不同的反应底物,反应中没有任何的交叉干扰。
想问下各位,南京建成购买的测组织MPO的试剂盒能否用酶标仪测啊?说明书上只写了用比色皿测,但由于比色皿操作比较慢,就在想能不能加在96孔板里用酶标仪测。有经验的小伙伴麻烦分享下经验。如果可以用酶标仪测,那么操作步骤还是按那个比色皿法的说明书来吗,步骤有没有哪里不同的??感谢各位!
特点
快速的分析能力有效的在3.5秒内完成96 well的样品检测,有样品震荡与恒温装置
