CD28 is a 44 kD disulfide-linked homodimeric type I glycoprotein. It is a member of the immunoglobulin superfamily and is also known as T44 or Tp44. CD28 is expressed on most T lineage cells, NK cell subsets, and plasma cells. CD28 binds both CD80 and CD86 using a highly conserved motif MYPPY in the CDR3-like loop. CD28 is considered a major co-stimulatory molecule, inducing T lymphocyte activation and IL-2 synthesis, and preventing cell death. In vitro studies indicate that ligation of CD28 on T cells by CD80 and CD86 on antigen presenting cells provides a costimulatory signal required for T cell activation and proliferation.

Dilutions: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is 5 microl per million cells or 5 microl per 100 microl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.* Pacific Blue(TM) has a maximum emission of 455 nm when it is excited at 405 nm. Prior to using Pacific Blue(TM) conjugate for flow cytometric analysis, please verify your flow cytometer's capability of exciting and detecting the fluorochrome. ** Pacific Blue(TM) is a registered trademark of Molecular Probes, Inc.
