CHEK1
CHEK1,别名CHK1、OZEMA21,是一种由人类基因编码的Ser/Thr蛋白激酶家族成员,对响应DNA损伤或未复制DNA存在的检查点调节细胞周期停滞至关重要。CHEK1可整合来自ATM和ATR两种参与DNA损伤应答的细胞周期蛋白的信号,这些蛋白在减数分裂前期I中也与染色质相关。CHEK1对CDC25A蛋白磷酸酶的磷酸化是必需的,以使细胞响应双链DNA断裂而延迟细胞周期进程。CHEK1参与DNA损伤检查点信号传导、G2/M转换的有丝分裂细胞周期以及内细胞团细胞增殖等过程。它在染色质、核和复制叉中发挥作用,并在多种组织中表达,包括肾上腺髓质、早孕、性腺、直觉和来自神经嵴的躯干间充质。CHEK1的异常表达与多种癌症相关,包括胰腺癌。

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).
