Wisteria floribunda lectin (WFA, WFL), Biotinylated

Wisteria Floribunda Lectin (WFA, WFL), Biotinylated, 2 mg. Though its binding specificity is not completely clear, this lectin appears to preferentially bind carbohydrate structures terminating in N-acetylgalactosamine linked alpha or beta to the 3 or 6 position of galactose. This lectin has been used to fractionate lymphocyte populations and, though not mitogenic, elicits the production of lymphokines from murine splenocytes. Biotinylated WFL has an appropriate number of biotins bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated biotins and is preserved with sodium azide.
