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 E18 antibody blocks the binding of 37.51 antibody to CD28 and costimulates T cell activation and proliferation.

Product Details

Verified Reactivity: Mouse
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: A20 cells and recombinant mCD28Ig
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with FITC under optimal conditions.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application: FC - Quality tested
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 ≤ 1.0 µg per 10⁶ cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
Excitation Laser: Blue Laser (488 nm)
Application Notes: Additional reported applications (for the relevant formats) include: in vitro costimulation of T and NK cells¹, in vitro blocking of allogeneic mixed leukocyte response and inhibition of MHC-unrestricted CTL cytotoxicity, and in vitro induction of thymocyte differentiation. The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 122004).
