Alternative Name:CD8α; CD8A; CD8 alpha; Leu2a; MAL; T8; p32｜Application:Flow cytometry (Qualified)｜Brand:BD OptiBuild?｜Concentration:0.2 mg/ml｜Entrez Gene ID:925｜Immunogen:Human Peripheral Blood T Cells｜Isotype:Mouse BALB/c IgG1, κ｜Reactivity:Human (Tested in Development)｜Regulatory Status:RUO｜RRID:AB_2871067｜Storage Buffer:Aqueous buffered solution containing ≤0.09% sodium azide.｜Workshop Number:I T51,74; III T118,152,571｜描述： The SK1 monoclonal antibody specifically binds to CD8 alpha (CD8α). CD8α is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily. CD8α is expressed by the majority of thymocytes, by subpopulations of??αβ T cells and γδ T cells and by some NK cells. Cell surface CD8α is expressed either as a disulfide-linked homodimer (CD8αα) or as a heterodimer (CD8αβ) when disulfide-bonded to a CD8 beta chain (CD8β). CD8-positive αβ T cells coexpress both CD8αα homodimers and CD8αβ heterodimers whereas some γδ T cells and NK cells express CD8αα homodimers.??CD8 plays important roles in T cell activation and selection. The extracellular IgSF domain of CD8α binds to a non-polymorphic determinant on HLA class I molecules (α3 domain) and enables CD8 to function as a co-receptor with MHC class I-restricted TCR during T cell recognition of antigen. The cytoplasmic domain of CD8α associates with Lck, a Src family protein tyrosine kinase that is involved in intracellular signaling. ｜商品通知：This antibody was developed for use in flow cytometry.The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.Researchers should determine the optimal concentration of this reagent for their individual applications.An isotype control should be used at the same concentration as the antibody of interest.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page BD Horizon Brilliant Stain Buffer is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,575,303; 8,354,239.BD Horizon Brilliant Ultraviolet 661 is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,227,187; 8,575,303; 8,354,239.｜推薦的實(shí)驗(yàn)流程： For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment.??Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.??The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.??More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat.
