CD4+ T cells can be subdivided into naïve, memory, and effector subsets based on their expression of CD45RA and CCR7. Naïve T cells express high levels of CD45RA and CCR7, whereas memory T cells express variable levels of these markers. Expression of CCR7 and CD45RA allows differentiation of memory T cells into central (CCR7+CD45RA-) and effector memory (CCR7-CD45RA-) subsets. This panel of antibodies is designed for characterizing these three CD4+ T cell subsets, which may exhibit variations following antigenic stimulation such as viral infection or vaccination.
Each lot of these antibodies is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 20 microL per million cells or 20 microL per 100 microL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
