CD2 antibodies – functional grade, human

Clone: LT2
The CD2 antibody recognizes the human CD2 antigen, a 50 kDa single-chain transmembrane glycoprotein also known as LFA-2 or receptor for sheep erythrocytes. It reacts with 80–90% of peripheral blood lymphocytes and more than 95% of thymocytes. The antibody recognizes all T cells and a subset of natural killer (NK) cells. Activation and proliferation of T cells can be induced by interaction of the T cell receptor with peptide-MHC complexes expressed on the surface of antigen-presenting cells (APCs). The T cell receives a signal transduced through the CD3 complex. Cytokines or other costimulatory signals are required in addition. Activated T cells can be used for any downstream processes, such as cytokine analysis or immunoprecipitation.


The CD2-Biotin – functional grade antibody is suited for functional assays, for example, activation and expansion of T cells together with CD3-Biotin – functional grade antibody, CD28-Biotin – functional grade antibody, and Anti-Biotin MACSiBead™ Particles, cell culture grade.
