- SynonymNTRK2,TRKB,GP145-TrkB
- SourceHuman TrkB, His Tag (NT2-H5228) is expressed from human 293 cells (HEK293). It contains AA Cys 32 - His 430 (Accession # AAH31835).Predicted N-terminus: Cys 32Request for sequence
- Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 45.2 kDa. The protein migrates as 60-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human TrkB, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
- BackgroundNeurotrophic tyrosine kinase receptor type 2 (NTRK2) is also known as BDNF/NT-3 growth factors receptor, Tropomyosin-related kinase B (TRKB) and TrkB tyrosine kinase, which belongs to the protein kinase superfamily or Tyr protein kinase family. Insulin receptor subfamily. NTRK2 / TrkB contains two Ig-like C2-type (immunoglobulin-like) domains, two LRR (leucine-rich) repeats, one LRRCT domain, one LRRNT domain, one protein kinase domain. NTRK2 / Trk-B is expressed in the central and peripheral nervous system. The catalytic activity of NTRK2 is “ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate”. NTRK2 / TrkB involved in the development and the maturation of the central and the peripheral nervous systems through regulation of neuron survival, proliferation, migration, differentiation, and synapse formation and plasticity.

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!

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。
