Description
| Like PTL I, this lectin binds preferentially to N-acetylgalactosamine, with this sugar also being the most inhibitory monosaccharide. However, in contrast to PTL I, this lectin prefers the β anomeric configuration. PTL II shows a high affinity toward blood group H structures and the T-antigen. PTL I and PTL II also differ in their erythrocyte agglutinating properties. Biotinylated PTL II 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 sodium azide. This biotinylated lectin is an ideal intermediate for examining glycoconjugates using the Biotin-Avidin/Streptavidin System. First the biotinylated lectin is added, followed by the VECTASTAIN® ABC Reagent, Avidin D conjugate, or streptavidin derivative. Inhibiting Sugar: 100 mM N-acetylgalactosamine |
