PSF抗体(D-8)是一种IgG1 κ小鼠单克隆PSF抗体,可通过WB、IP、IF、IHC(P)和ELISA等方法检测小鼠、大鼠和人类来源的PSF。PSF抗体(D-8)有非偶联抗PSF抗体形式,也有多种偶联形式的抗PSF抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。前mRNA剪接是基因表达翻译后调控的关键步骤。从mRNA中去除内含子序列的过程是一个两步酶促反应,需要剪接体(一种大型多组分核糖核蛋白复合物)的作用。多嘧啶束结合蛋白(PTB)相关剪接因子(PSF)是一种普遍表达的蛋白质,它与PTB(也称为hnRNP I)形成复合物,这对于早期剪接体的形成是必需的,并且对催化步骤II至关重要。PSF蛋白包含两个RNA识别基序(RRMs)、一个富含脯氨酸和谷氨酰胺的氨基末端结构域,以及两个羧基末端核定位信号。PSF定位于核内被称为斑点的点状结构,而核仁中则不存在这种结构。PSF定位到斑点依赖于第二个RRM基序的存在。PSF还可以与甲状腺激素受体和视黄酸受体的DNA结合域(DBDs)结合,通过招募HDACs到DBDs来发挥抑制作用。PSF在发育过程中的神经元中表达,可能参与神经元的分化和成熟。在髓系细胞中,PSF会被蛋白水解切割,产生一个较短的片段。

仅限研究使用。不适用于诊断和治疗用途。

What application is the blocking peptide sc-271796 P appropriate for?

Asked by: jerojero
Thank you for your question. The blocking peptide is intended for use as a negative control, by pre-adsorbing the mouse monoclonal antibody against the antigen.
