Bioactivity-FACS
 CD28 FACS

Flow cytometric analysis of Human peripheral blood lymphocytes respectively staining with PE-Labeled Monoclonal Anti-Human CD28 Antibody, Mouse IgG1 (Cat. No. CD8-PCFC1) at 1:50 dilution (2 μL of the antibody stock solution corresponds to labeling of 1e6 cells in a final volume of 100 µL), compared with isotype control antibody. PE signal was used to evaluate the binding activity (QC tested).

 CD28 FACS

Non-specificity of PE-Labeled Monoclonal Anti-Human CD28 Antibody, Mouse IgG1 (Cat. No. CD8-PCFC1) binding to CD3- cells present in human PBMC. Human PBMCs were simultaneously stained with FITC anti-human CD3 Antibody and PE-Labeled Monoclonal Anti-Human CD28 Antibody, Mouse IgG1 (2 μL of the antibody stock solution corresponds to labeling of 5e5 cells in a final volume of 100 µL), washed and then analyzed with FACS. FITC negative signals and PE positive signals were used to evaluate the non-specific binding activity to human CD3- cells (Routinely tested).

  • Background
    T-cell-specific surface glycoprotein CD28 is also known as TP44, is a single-pass type I membrane protein which contains one Ig-like V-type (immunoglobulin-like) domain. is one of the molecules expressed on T cells that provide co-stimulatory signals, which are required for T cell activation. CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2). When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells.
