CD19 is a 95 kD type I transmembrane glycoprotein also known as B4. It is a member of the immunoglobulin superfamily expressed on B-cells (from pro-B to blastoid B cells, absent on plasma cells) and follicular dendritic cells. CD19 is involved in B cell development, activation, and differentiation. CD19 forms a complex with CD21 (CR2) and CD81 (TAPA-1), and functions as a BCR co-receptor.
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis.
For test sizes, the suggested use of this reagent for immunofluorescent staining is 5 microL per 106 cells in 100 microL volume.
For microg sizes, the suggested use of this reagent for immunofluorescent staining is ≤ 0.5 microg per 106 cells in 100 microL volume.
It is recommended that the reagent be titrated for optimal performance for each application.
* Pacific Blue™ has a maximum emission of 455 nm when it is excited at 405 nm. Prior to using Pacific Blue™ conjugate for flow cytometric analysis, please verify your flow cytometer's capability of exciting and detecting the fluorochrome.
