Applications
Key Applications T Cell Co-stimulation
Flow Cytometry
Frozen Sections
Immunoprecipitation
Application NotesFlow Cytometry (5 µg/ml)
Frozen Sections (see comments)
Immunoprecipitation (see comments)
T cell Co-stimulation (see comments)
Application CommentsMonomeric and cross-linked antibody will stimulate expression of IL-2 from CD28+ cells. FACS was performed on 5x105 cultured HPB-MLT cells using anti-CD28 antibody at 5 µg/ml and FITC-conjugated goat anti-mouse IgG. This antibody is also reported to work for frozen sections and immunoprecipitation. Variables associated with assay conditions will dictate the proper working dilution.

    DescriptionProtein A purified mouse monoclonal antibody. Recognizes the CD28 protein.
    BackgroundHuman CD28 is an important co-stimulatory molecule found on all CD4+ T cells and ~50% of CD8+ T cells. T cell activities attributed to CD28 include prevention of anergy, induction of cytokine gene transcription, stabilization of cytokine mRNA, and activation of CD8+ cytotoxic T lymphocytes. The ligands for CD28, known as CD80 (B7-1) and CD86 (B7-2), are monomeric transmembrane glycoproteins.
