Comparison of hydroxylated print additives on antibody microarray performance.


ABSTRACT: Various hydroxylated additives were added to antibody print buffers at different concentrations to stabilize printed antibodies during normal array spot desiccation on commercial polymer-coated microarray slides. Polyvinyl alcohol addition to print buffers produced the most regular spot morphologies, homogeneous intra-spot antibody distribution, uniform fluorescence intensity, and improved analyte capture activity, maintained up to 1 month at 4 degrees C for capturing model analytes, anti-human IL-1beta, IL-4, and TNFalpha, on these microarraying slides.
