Millipore of Billerica, Mass., has received US Patent No. 7,618,592, "Detachable engageable microarray plate liner." The patent provides a plate liner for controlling pendant drop formation. The plate liner is configured to engage onto a specific pre-defined microarray such that the force required to manually detach it from the microarray is substantially less than the force that would result in the disengagement, fracturing, division, or otherwise separation of the complementary array of wells and underdrains that constitute the microarray. Specifically, the plate liner composes an array of hermetic spout isolators that will register with the underdrains when the plate liner is engaged onto the pre-defined microarray. When engaged, any fluid placed in said wells and passing into the underdrains is hermetically blocked from flowing past the hermetic spout isolators.
Agilent Technologies has received US Patent No. 7,618,777, "Composition and method for array hybridization." The patent claims a method of hybridizing an array by contacting a first oligonucleotide bound to a silaceous surface with a second unbound oligonucleotide in the presence of an aqueous mixture composed of a superwetting agent. According to the patent, the contacting is done under conditions that provide for hybridization of the first oligonucleotide with the second oligonucleotide. The contacting is done in the presence of a moving gas bubble that dispels the aqueous mixture across the silaceous surface.
Ronald Gebing of Westminister, Md., has received US Patent No. 7,618,809, "Microarrayer with coaxial multiple punches." The patent claims a microarrayer apparatus for constructing arrays of biological material from donor cores. The described apparatus includes a donor punch, a recipient punch, and a stylus mounted for independent coaxial movement along a common punch axis. The recipient punch cooperates with the stylus when ejecting a donor core from the donor punch to minimize deformation of the donor core, according to the patent.
Tecan of Mannedorf, Switzerland, has received US Patent No. 7,618,812, "Device and process unit for providing a hybridization chamber." The patent claims a device that includes a hybridization chamber for hybridizing nucleic acid samples, proteins, or tissue sections on a slide. The device includes a surface, lines for supplying and removing media, a specimen supply line and an agitating device. The agitation device includes a membrane that separates a specific pressure chamber that is filled with fluid via one of the lines, from an agitation chamber, which is connected via an agitation line to the hybridization chamber. Four such devices can be combined into a process unit for providing a hybridization chamber, according to the patent.
Illumina has received US Patent No. 7,619,819, "Method and apparatus for drug product tracking using encoded optical identification elements." The patent claims a method and apparatus for drug-product tracking. The method relies on diffraction grating-based encoded optical identification elements, including an optical substrate containing at least one diffraction grating. The encoded element may be used to label any desired item, such as drugs or medicines, or other pharmaceutical or health care products or cosmetics, according to the patent. The label may also be used for other purposes, such as for sorting, tracking, identification, verification, authentication, or for other purposes.
