Human CD28 Antibody
The staining effect of Human CD28 antibody to CD28 of Human Peripheral Blood Lymphocytes by Flow cytometric analysis.
A: Lymphocytes were stained with PE-conjugated humanized CD28 antibody.
B: The binding effect of PE-conjugated human CD28 antibody(Red histograms) in the lymphocytes can be blocked by pre-incubation of the CD28 antibody (BD, 555725) for 20min (blue histograms).

Human CD28 Antibody
CD28+ T cell staining of lymphocytes using human CD28 antibody by Flow cytometric analysis.
Lymphocytes were stained with PE-conjugated humanized CD28 antibody and CD19-APC (BD, 555415).

Human CD28 Antibody, Agonist Activity
Effect of human CD28 antibody on stimulating IL-2 secretion of CD4 T cells co-activated with CD3 antibody. The isolated CD4+ T cells (1e5/well) were cultured in the 96-well cell plates pre-coated with 2 μg/mL human CD3 (humanized OKT3) antibody (10977-H001) in the culture medium containing serial dilutions of CD28 antibody. 48 hours later, IL-2 secretion in the medium was measured by IL-2 Quantitative ELISA Kit.

CD28/TP44 研究背景

CD28 (Cluster of Differentiation 28) is a disulphide-bonded glycoprotein belonging to the immunoglobulin (Ig) superfamily, and structurally consists of a single Ig V-like extracellular domain, a transmembrane domain and an intracellular domain. Mouse CD28 is constitutively expressed on the surface of all murine T cells and on developing thymocytes as disulfide-linked homodimers or as monomers. CD28 can binds the B7-1 and B7-2 ligand, and together perform important functions in the T and B cell response pathways. B7/CD28 family members, which can augment or antagonize T-cell receptor signaling, in the regulation of central and peripheral T-cell tolerance. CD28 is thus involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival.
