此外 CD8 抗体包括 CD8-α 和 CD8-β

CD8抗体（2.43）是一种鼠单克隆IgG2b抗体，可通过免疫荧光（IF）和流式细胞术（FCM）检测小鼠样本中的CD8。CD8是一种重要的细胞表面糖蛋白，可形成异二聚体，通常以αα或αβ链复合物的形式存在，通过与抗原呈递细胞呈现的I类主要组织相容性复合物（MHC）分子结合，在免疫反应中发挥重要作用。这种相互作用对于表达CD8的T细胞毒性细胞至关重要，因为CD8可增强T细胞受体（TCR）对抗原的识别，从而增强对感染或恶性细胞的免疫反应。此外，表达CD8的T细胞与维持低水平HIV表达有关，这表明它们不仅对直接细胞毒性，而且对调节病毒载量都很重要。CD8能够促进抗原识别并增强TCR亲和力，这凸显了CD8在适应性免疫中的重要性，使抗CD8抗体（2.43）成为研究人员在小鼠模型中研究T细胞动态和免疫反应的宝贵工具。

Can CD8 (2.43): sc-18860 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: AbPolly
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, CD8 (2.43): sc-18860 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.
