Figure Lengend Snippet: Direct and indirect method for thrombin detection. ( a ) Fluorescence signal (635 or 532 nm) plot of thrombin aptamer microarray after the incubation of thrombin and TBA2-Cy5 (direct method, red squares, 635 nm) or thrombin and TBA2-biotin plus Cy3-streptavidin (indirect method, green dots, 532 nm) and ( b ) relative microarray images. Tested thrombin dilutions were: 200 nM–100 nM–50 nM–10 nM–5 nM–1 nM–0 nM. TBA2-Cy5 (red squares) or TBA2-biotin (green dots) concentration was 400 nM. For the indirect method the microarray slide was incubated for 1 h with Cy3-streptavidin, for a total incubation time of two hours in all cases.
Article Snippet: TBA1 aptamers were loaded into microarray plates and submitted to the Microarray Spotter (Versarray Chip Writer Pro System, BioRad) for slide printing, using Telechem SMP3 microspotting pins (Arrayit, Sunnyvale, CA, USA).
