CapitalBio of Beijing has received US Patent No. 7,578,612, "Three-phase tilting agitator for microarrays." The patent describes a three-phase tilting agitator for microarrays, including large area microarrays, that provides experimentally verified improvements in hybridization intensity and uniformity. According to the patent's abstract, motion is coupled from a single motor to a sample holder via three suspension tethers. The microarrays may be immersed in a water bath during agitation to maintain a temperature for the hybridization reaction.
