Application:

FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation1, in vitro costimulation of T and NK cells1, in vitro blocking of allogeneic mixed leukocyte response and inhibition of MHC-unrestricted CTL cytotoxicity3,4, in vitro induction of thymocyte differentiation2,5-9,11, and immunohistochemical staining of acetone-fixed frozen sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
* PerCP/Cy5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.

Description:

CD28 is a 44 kD glycoprotein, also known as Tp44 or T44. It is a member of the Ig superfamily, expressed on thymocytes, most peripheral T cells, and NK cells. In association with CD80 (B7-1) and CD86 (B7-2), CD28 acts as the second signal for T and NK cell activation and proliferation. The 37.51 antibody has been reported to augment in vitro T cell proliferation and cytokine production, and promote CTL development.

Other Names: Tp44, T44
Structure: Ig superfamily, 44 kD
Distribution: Thymocytes, CD4+, CD8+ peripheral T cells, NK cells
Function: Costimulates T and NK cells
Ligand Receptor: CD80 (B7-1), CD86 (B7-2)
