CHEK1
CHEK1，別名CHK1、OZEMA21，是一種由人類基因編碼的Ser/Thr蛋白激酶家族成員，對響應DNA損傷或未復制DNA存在的檢查點調節細胞周期停滯至關重要。CHEK1可整合來自ATM和ATR兩種參與DNA損傷應答的細胞周期蛋白的信號，這些蛋白在減數分裂前期I中也與染色質相關。CHEK1對CDC25A蛋白磷酸酶的磷酸化是必需的，以使細胞響應雙鏈DNA斷裂而延遲細胞周期進程。CHEK1參與DNA損傷檢查點信號傳導、G2/M轉換的有絲分裂細胞周期以及內細胞團細胞增殖等過程。它在染色質、核和復制叉中發揮作用，并在多種組織中表達，包括腎上腺髓質、早孕、性腺、直覺和來自神經嵴的軀干間充質。CHEK1的異常表達與多種癌癥相關，包括胰腺癌。

All lanes: Chk1 antibody at 1:1000
Secondary

IHC image of CSB-RA176809A0HU diluted at 1:100 and staining in paraffin-embedded human small intestine 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℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
Immunofluorescence staining of Hela Cells with CSB-RA176809A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeated by 0.2% TritonX-100, and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4℃. Nuclear DNA was labeled in blue with DAPI. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Rabbit IgG (H+L).
