Telechem/Arrayit has introduced a new scanner as part of its protein microarray product package. The SpotWare Colorimetric microarray scanner, based on CCD line-scanning technologies, uses a colorimetric system that complements fluorescent scanning and allows researchers to use pigmented labels such as horseradish peroxidase, alkaline phosphatase, gold and silver developers, and secondary antibodies. The scanner holds standard glass microarrays, including those with coated substrates, and has resolution adjustable from 5 to 20 microns, capable of scanning a square centimeter in 30 seconds at 10 micrometer resolution. The scanner sells for $3,895. The instrument currently reads one array. In the future, there are plans to increase capacity for reading 12 arrays at a time, the company said. The scanner is desktop size and weighs approximately 7 pounds.
