Figure 2From: Direct patterning of probe proteins on an antifouling PLL-g-dextran coating for reducing the background signal of fluorescent immunoassays Fluorescence images after Cy3-labelled GST interaction on the printed PLL-g-dextran glass slide printed with anti-GST Abs. The target molecules have preferentially interacted with the anti-GST Ab patterns. Scale bar: 300 μm. Inset is an enlarged view of four 160 μm size interaction spots.Back to article page
