Description
Specificity:
Mouse Anti-Human CD2 (Clone G11) recognizes an epitope on Human CD2. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Antigen Distribution:
The CD2 antigen is present on approximately 80% of normal peripheral blood lymphocytes, >95% of thymocytes, 100% of mature circulating T-cells and a subset of NK cells.

Background:
Appropriate pairs of anti-CD2 antibodies will stimulate peripheral T-cell proliferation and effector function.1 The CD2 molecule has been shown to be the receptor for leukocyte function antigen (LFA-3/CD58),2 the binding of which augments T-cell activation mediated by the T-cell antigen receptor (TCR).3 Anti-Human CD2 can be used to deplete CD2 positive cells by complement-mediated cytotoxicity. Analyses of NK lymphocyte subsets and identification of lymphomas and leukemias of T-cell origin have been done using Anti-CD2 antibodies.

Reporter Molecule:
DyLight® 550 conjugated antibodies absorb light maximally around 562 (± 4 nm) and fluoresce with a peak around 576 nm. They are brighter than TRITC conjugates, and they are equal in brightness to Cy3 and Alexa Fluor 555. All Dylight® 550 antibodies are recommended for maximum sensitivity in all immunofluorescence detection procedures within the orange-red portion of the visible spectrum.
