Affinity purified Succinylated concanavalin A (Succ-Con A) is derived from native lectin concanavalin A (Con A). It is a nonagglutinating lectin that has a carbohydrate specificity for Î± linked mannose and glucose, with a sugar elution of Î±-methlyglucoside + Î±-methlymannoside. Succ-Con A have been studied for their effects to induce marked proliferation of human peripheral blood lymphocytes. Succ-Con A exhibits mitogenic action equal to native Con A and both increase lymphocytes levels of cyclic GMP. Unlike Con A, Succ-Con at high concertation does not decrease mitogenic activity. Succ-Con A reversibly prevents the growth of normal cells and restores a normal growth phenotype to transformed cells. Cy5, when bound to Succinylated Concanavalin A Lectin (Succ Con A), can show the binding pattern of this lectin in cellular imaging and flow cytometry. The excitation wavelength required for Cy5 to fluoresce is high enough to avoid overlap with most other fluorochromes, making it useful for dual-labeling experiments. Because of this high excitation, there is typically less background from autofluorescence of biological specimens.
