CHEK2
CHEK2,全稱為細(xì)胞周期檢查點(diǎn)激酶2,常被簡稱為CHK2,也有RAD53同源物等別名。它是細(xì)胞內(nèi)關(guān)鍵的“安全衛(wèi)士”,當(dāng)DNA遭遇損傷時(shí)會(huì)迅速激活,推動(dòng)細(xì)胞暫時(shí)停止分裂進(jìn)程,為DNA修復(fù)創(chuàng)造條件;若損傷無法逆轉(zhuǎn),還會(huì)引導(dǎo)細(xì)胞啟動(dòng)程序性死亡,防止異常細(xì)胞增殖擴(kuò)散。
CHEK2功能異常與多種疾病密切相關(guān),最突出的是乳腺癌、卵巢癌等惡性腫瘤——攜帶CHEK2突變的個(gè)體,患癌風(fēng)險(xiǎn)顯著上升,部分遺傳性腫瘤綜合征(如Li-Fraumeni樣綜合征)也與它的突變有關(guān)。在藥物研發(fā)領(lǐng)域,針對CHEK2的小分子抑制劑是研究熱點(diǎn),部分候選藥物已進(jìn)入臨床試驗(yàn)階段,它們有望通過抑制異常CHEK2的活性,提升腫瘤細(xì)胞對放化療的敏感性,為相關(guān)突變患者提供新的治療選擇。

IHC image of CSB-RA828105A0HU diluted at 1:100 and staining in paraffin-embedded human placenta 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.
Immunofluorescence staining of Hela cell with CSB-RA828105A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
Overlay Peak curve showing Hela cells stained with CSB-RA828105A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde 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 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
CHEK2 Antibody (CSB-PA005339LA01HU)
驗(yàn)證數(shù)據(jù)
IHC image of CSB-PA005339LA01HU diluted at 1:200 and staining in paraffin-embedded human testis 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 biotinylated secondary antibody and visualized using an HRP conjugated SP system.
