EGFR(Epidermal Growth Factor Receptor)是一個(gè)經(jīng)典的跨膜蛋白,屬于酪氨酸激酶型受體。EGFR廣泛分布于哺乳動(dòng)物上皮細胞、成纖維細胞、膠質(zhì)細胞、角質(zhì)細胞等細胞表面,EGFR信號通路對細胞的生長(cháng)、增殖和分化等生理過(guò)程發(fā)揮重要的作用。EGFR通過(guò)與配體結合而激活,介導上皮生長(cháng)因子(EGF)細胞增殖和信號傳導。EGFR被配體激活后啟動(dòng)胞內信號傳導,經(jīng)過(guò)細胞質(zhì)中銜接蛋白、酶的級聯(lián)反應,轉錄因子激活基因的轉錄,介導細胞遷移和黏附等過(guò)程,且與腫瘤的形成和惡化密切相關(guān)。許多研究表明EGFR在非小細胞肺癌、頭頸部腫瘤、乳腺癌、膀胱癌、結直腸癌、卵巢癌等多種腫瘤中存在突變或高表達。因此,已經(jīng)有很多研究把EGFR作為腫瘤的治療靶點(diǎn)。近年來(lái),靶向EGFR藥物已成為抗腫瘤藥物研究的熱點(diǎn)。

EGFR Recombinant Monoclonal Antibody 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.


Overlay Peak curve showing NIH/3T3 cells stained with CSB-RA159341MA1HU (red line) at 1:100. Then 10% normal goat serum was Incubated to block non-specific protein-protein interactions followed by the antibody (1μg/1*106cells) for 45 min at 4°C. 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.
