(A) SPRi sensorgrams showing shifts caused by injecting 100 ng/mL anti-GT1b in 10 % serum on GT1b ganglioside surface (Blue), GM1 ganglioside surface (Red), GA1 ganglioside surface (Green), and PFDTS surface (Black). Number indicate experimental conditions/procedure: 1) Rinse after 10 % serum, 2) Inject 100 ng/mL anti-GT1b in 10 % serum, 3) Incubation, and 4) Rinse. (B) SPR image of the ganglioside arrays. Color indicates functionalized surface in each row.
