| Abstract: | Microarraying technologies have emerged as key tools for determining genomic expression. The quality of gene arrays is reliant on spotting pins for production of uniform spots, which are consistent in volume, shape, size and alignment.Point Technologies, Inc., has developed an advanced spotting technology. Emphasis has been placed on producing the “perfect spots” customized to each microarraying application. Uniform surface texturing such as highly polished or matte finishes, and hydrophilic/hydrophobic zonal coating is produced using Point Technologies' proprietary micro-machining technology. Microfabrication also permits the production of advanced pin designs, and high density, high throughput print-head assemblies of 1536 pins and greater. Point Technologies specializes in the micro-electrochemical machining of spotting pins in any size, shape and configuration.Presented data will demonstrate spotting pin design solutions, such as: variety of tip dimensions, surface finishes, specialized coatings, and material options instrumental in producing the ideal spot size, shape and spot density during extended usage. |
