Human peripheral blood lymphocytes stained with biotinylated anti-human CD3 (clone SK7, filled histogram) or biotinylated mouse IgG1, κ (open histogram) isotype control, followed by SAV-PE -
Human PBMCs, stimulated with 1 µg/ml of LPS for 8 h and treated with Brefeldin A during the last 4 h, were prepared by cytospin, fixed and permeabilized on a slide and then treated with endogenous biotin blocking kit (Vector labs). Slides were stained with anti-human CD3 biotin (clone SK7) and DyLight™ 649 streptavidin (green) and counterstained with DAPI (blue). Images were acquired with an Olympus FV10i confocal microscope.

CD3ε is a 20 kD chain of the CD3/T-cell receptor (TCR) complex, which is composed of two CD3ε, one CD3γ, one CD3δ, one CD3ζ (CD247), and a T-cell receptor (α/β or γ/δ) heterodimer. It is found on all mature T cells, NK T cells, and some thymocytes. CD3, also known as T3, is a member of the immunoglobulin superfamily that plays a role in antigen recognition, signal transduction, and T cell activation.
