ERBB2

ERBB2,即人表皮生長(zhǎng)因子受體2,別名NEU、HER-2、CD340、HER2,由人類(lèi)ERBB2基因編碼,該基因位于7號(hào)染色體上。ERBB2蛋白是一種跨膜酪氨酸激酶受體,屬于HER家族成員之一,由胞外配體結(jié)合域、跨膜結(jié)構(gòu)域和胞內(nèi)結(jié)構(gòu)域三部分組成。其作用機(jī)制涉及與其他HER家族成員結(jié)合形成異二聚體,增強(qiáng)激酶的激活作用并介導(dǎo)下游信號(hào)通路的活性,如MAPK和PI3K/AKT信號(hào)通路。
ERBB2的異常激活,包括基因擴(kuò)增、過(guò)表達(dá)和突變,與多種癌癥的發(fā)生發(fā)展有關(guān),如乳腺癌、非小細(xì)胞肺癌、胃癌和子宮內(nèi)膜腫瘤等。ERBB2基因擴(kuò)增與乳腺癌的預(yù)后不良相關(guān),已成為近30%乳腺癌患者生物治療的重要靶點(diǎn)。

CSB-RA159341MA1HU

IHC image of CSB-RA159341MA1HU diluted at 1:50 and staining in paraffin-embedded human lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

CSB-RA159341MA1HU

IHC image of CSB-RA159341MA1HU diluted at 1:50 and staining in paraffin-embedded human pancreatic tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

CSB-RA159341MA1HU

Overlay Peak curve showing NIH/3T3 cells stained with CSB-RA159341MA1HU (red line) at 1:100. The cells were fixed in 4% formaldehyde (15min) and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-Rabbit IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1μg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
