Apogent Discoveries of Hudson, NH, is introducing MicroSpot C ceramic pins for printing microarrays. The pins are designed for use with the company’s MicroGrid arrayer. The product will produce more spots per source visit and requires no pre-blotting. It can be used for printing proteins, amino acids, peptides, oligos, and nucleic acids. Apogent says the chemically inert pins have been tested with up to 1 million hits against a glass slide without deformation or changes to the morphology of the spots.
