Accelr8 Technology of Denver has introduced two new slides for microarraying. The slides include a covalent amine reactive and a thiol reactive product. They are intended for use in both DNA and protein arraying. Like the company’s Biotin slides, they use its OptiChem surface chemistry. The slides are said to have low non-specific binding, low background fluorescence, and optimized surface energy for array spotting, high probe binding capacity, and covalent probe attachment.
