Figure 4From: Drop drying on surfaces determines chemical reactivity - the specific case of immobilization of oligonucleotides on microarrayspH dependence of oligonucleotide immobilization. Influence of pH and buffer phosphate concentration on immobilization of aACG and ACG on 3D hydrogel after 22 hrs. Large error bars for aACG in 10 mM phosphate spotting buffer are due to poor spot morphology.Back to article page
