- SynonymMET,AUTS9,HGFR,RCCP2,c-Met
- SourceHuman HGF R, His Tag (MET-H5227) is expressed from human 293 cells (HEK293). It contains AA Glu 25 - Thr 932 (Accession # AAI30421.1).Predicted N-terminus: Glu 25Request for sequence
- Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus. The mature form of HGFR is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. Each α and β chain has a calculated MW of 32.5 kDa and 70.2 kDa. The protein migrates as 40-45 kDa and 85-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>92% 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.

Immobilized Human HGF/Hepatocyte Growth Factor at 2 μg/mL (100 μL/well) can bind Human HGF R, His Tag (Cat. No. MET-H5227) with a linear range of 0.039-0.313 μg/mL (Routinely tested).
- BackgroundHepatocyte growth factor receptor (HGFR) is also known as mesenchymal-epithelial transition factor (MET), c-Met, andis a glycosylated receptor tyrosine kinase that plays a central role in epithelial morphogenesis and cancer development. HGFR protein possesses tyrosine-kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor. HGFR is normally expressed by cells of epithelial origin, while expression of HGF is restricted to cells of mesenchymal origin. Upon HGF stimulation, HGFR induces several biological responses that collectively give rise to a program known as invasive growth. Abnormal HGFR activation in cancer correlates with poor prognosis, where aberrantly active HGFR triggers tumor growth, formation of new blood vessels (angiogenesis) that supply the tumor with nutrients, and cancer spread to other organs (metastasis). HGFR is deregulated in many types of human malignancies, including cancers of kidney, liver, stomach, breast, and brain. Normally, only stem cells and progenitor cells express HGFR, However, cancer stem cells are thought to hijack the ability of normal stem cells to express HGFR, and thus become the cause of cancer persistence and spread to other sites in the body. Various mutations in the HGFR gene are associated with papillary renal carcinoma. HGFR mediates a complex program known as invasive growth. Activation of HGFR triggers mitogenesis, and morphogenesis.

利用NheI和HindIII双酶切插入目的片段,为什么双酶切有目的片段和切开的质粒,测序却没有?
并且测序后在NheI位点后的序列变成了-GGCTAGGTAC-Kpn位点(CGTTTAAACTTAAGCTTG消失。之前和之后的序列都相符),之间的怎么都没了?
请教高人,这样的问题怎么解决?
多谢
你所说的“测序酶”在一般情况下就是“聚合酶”。
因为目前的的测序方法主要就是借助聚合反应。
当然,有些测序方法(比如曾经的SOLiD系统)是利用连接反应,那么它用的“测序酶”肯定是连接酶。
估计,也就是这个原因有人把它。
两个基因大小分别230kb和450kb,酶切后,450kb的有目的条带,但很弱,230kb的质粒条带亮,其下方有一很微弱条带,用的酶分别是:Ncol和Spel体系是(Takara,两个酶切体系不同,用的官网推荐体系):
NcoI1μl
Spel1μl
10×KBuffer2μl
0.1%BSA2μl
DNA3ul
灭菌水upto20μl37℃4h电泳1h
期待着高手们的指点,谢谢。
【之前构建的4个重组质粒里也有两个出现这样的问题(aagtcc变成agtcc),但是酶切能切出插入的片段】
目前问测序公司得到的答复是样品可能不是单克隆,测序结果是不准确的,建议重新挑取单克隆测序。
不知道还有没有别的方法?
