Claspin抗体(B-6)是一种IgG1 κ型小鼠单克隆Claspin抗体(也称为CLSPN抗体),可通过WB、IP、IF和ELISA检测小鼠、大鼠和人源的Claspin蛋白。Claspin抗体(B-6)既可以是非偶联型抗Claspin抗体形式,也可以是多种偶联形式的抗Claspin抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。Claspin是一种重要的复制检查点控制蛋白,调节Chk1与上游调节激酶ATR之间的相互作用。Chk1介导细胞周期停滞,以响应DNA复制受阻或紫外线辐射造成的DNA损伤。Claspin在复制应激时在其Chk1结合域内发生磷酸化。该结构域由两个高度保守的约十个氨基酸的重复序列组成。每个重复序列都含有一个丝氨酸残基(丝氨酸864和丝氨酸895),该残基会发生磷酸化。Chk1和Claspin的结合促进Chk1与ATR和Rad9的相互作用,从而阻滞细胞周期。Claspin在细胞内的S/G2期最为丰富。

Good morning, I've been using Claspin Ab in RPE whole cell extract but I've never been able to see any band on my WB, even though my GAPDH was fine. I tried different dilution 1:2000 dilution to 1:100 in ABDIL but nothing. Do you have any recommandation ?

What is the recommended fixation method for immunofluorescence staining with Claspin (B-6): sc-376773 monoclonal antibody?

Asked by: TinTin
Thank you for your inquiry. We recommend fixing cells for 5 minutes in -10°C methanol and allowing to air dry. The full protocol can be viewed here: https://www.scbt.com/scbt/resources/protocols/immunofluorescence-cell-staining
