CD2, Sf9

Alternative Names: CD2 antigen, CD2, T11, T-cell surface antigen CD2, T-cell surface antigen T11/Leu-5, LFA-2, LFA-3 receptor, Erythrocyte receptor, Rosette receptor, SRBC.

CD2, also known as E-rosette receptor, T11, and lymphocyte function antigen-2 (LFA-2), is found on T cells, thymocytes, and a subset of natural killer cells. It acts as a receptor for sheep erythrocytes, human CD58 (LFA-3), and CD15s (Sialyl Lewis X). CD2 promotes the phosphorylation of proteins p56lck, p59fyn, CD3eta, and CD3epsilon when stimulated. Its functions include T cell activation, T- or NK-cell-mediated cytolysis, apoptosis in activated peripheral T cells, and the regulation of T cell anergy.

Storage Instruction

Reconstituted store at -20°C or -80°C.We recommend that single use aliquots are prepared to avoid freeze-thaw cycles.

Sample Prep Instruction

1. Thaw the vial on ice, spin briefly
2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
4. We recommend sterile filtering after dilution in media or the final working solution
