ERBB2,CD340,HER-2,neu,HER2,MLN19,NEU,NGL,TKR1
表達區(qū)間及表達系統(tǒng)(Source)
Human Her2, Tag Free (HE2-H5212) is expressed from human 293 cells (HEK293). It contains AA Thr 23 - Thr 652 (Accession # P04626-1).
Predicted N-terminus: Thr 23
蛋白結(jié)構(gòu)(Molecular Characterization)

This protein carries no "tag".
The protein has a calculated MW of 70.1 kDa. The protein migrates as 90-100 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介紹
人表皮生長因子受體2(HER2)亦稱ERBB2、HER-2、HER-2/neu、NEU、NGL、TKR1及c-erb B2,是一種可導致乳腺癌侵襲性增強的蛋白質(zhì)。該分子屬于ErbB蛋白家族(更常被稱為表皮生長因子受體家族),是一種細胞膜表面結(jié)合的受體酪氨酸激酶,通常參與調(diào)控細胞生長與分化的信號轉(zhuǎn)導通路。HER2被認為是一種孤兒受體,表皮生長因子家族中任何配體均無法將其激活。約30%的乳腺癌存在HER2基因擴增或其蛋白產(chǎn)物過表達現(xiàn)象,該受體在乳腺癌中的過表達與疾病復發(fā)率升高及預后不良密切相關(guān)。研究表明,HER2在發(fā)育過程、腫瘤發(fā)生、神經(jīng)肌肉接頭信號傳遞以及細胞生長與分化調(diào)控中均發(fā)揮重要作用。
