Alternative Name:Cd4; CD4 antigen; L3T4; Ly-4; T-cell surface antigen T4/Leu-3｜Application:Flow cytometry (Qualified)｜Brand:BD OptiBuild?｜Concentration:0.2 mg/ml｜Immunogen:A.TH mouse CTL clone A15.1.17｜Isotype:Rat LOU, also known as Louvain, LOU/C, LOU/M IgG2a, κ｜Reactivity:Mouse (Tested in Development)｜Regulatory Status:RUO｜RRID:AB_2870804｜Storage Buffer:Aqueous buffered solution containing ≤0.09% sodium azide.｜描述： The H129.19 monoclonal antibody specifically binds to the CD4 (L3T4) differentiation antigen expressed on thymocytes, a subpopulation of mature T lymphocytes (i.e., MHC class II-restricted T cells, including most T helper cells), and a subset of NK-T cells of all mouse strains tested. CD4 has also been detected on pluirpotent hematopoietic stem cells, bone marrow myeloid precursors, intrathymic lymphoid precursors, and a subset of splenic dendritic cells. CD4 is expressed on the plasma membrane of mouse egg cells and is involved in adhesion of the egg to MHC class II-bearing sperm. CD4 is an antigen coreceptor on the T-cell surface which interacts with MHC class II molecules on antigen-presenting cells. It participates in T-cell activation through its association??with the T-cell receptor complex and protein tyrosine Lck. The H129.19 antibody blocks binding of the anti-mouse CD4 antibodies GK1.5 and RM4-5, but not RM4-4 antibody. mAb H129.19 inhibits various responses of T helper cells to antigenic or mitogenic stimuli. ｜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.｜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. No. 563794).
