Gene Information

human ... CD28(940)

Specificity

This antibody reacts with the 44 kDa antigen found on a sub-population of T cells and activated B cells. These CD28+ CD8 cells are now known to be cytotoxic T cell precursors. The antibody does not react with B cells, granulocytes or monocytes. The ligand for CD28 is CD80 (B7) which is found on activated B cells suggesting a role for CD28 in T and B cell interaction

FUSION PARTNER: SP2/0

Immunogen

Human T lymphocytes

Application

This Anti-CD28 Antibody, clone 15E8 is validated for use in FC, FUNC for the detection of CD28.
To study the role of CD28 in T cell proliferation. The antibody will induce the proliferation of resting T lymphocytes.

This antibody will act in cell stimulation studies where it has been suggested that measuring T cell function in HIV infected asymptomatic patients may be an early indicator of AIDS, independent of CD4 + cell counts

Antithymidylates (AThy) constitute a class of drugs used in the treatment of cancers such as lung, colon, breast and pancreas. These drugs inhibit DNA synthesis by targeting the enzymes dihydrofolate reductase (DHFR) and/or thymidylate synthase (TYMS). AThys effectively inhibit cancer

Robust T-cell responses without autoimmunity are only possible through a fine balance between activating and inhibitory signals. We have identified a novel modulator of T-cell expansion named proliferation-induced lymphocyte-associated receptor (PILAR). Surface PILAR is markedly up-regulated on CD4 and, to
