20090197346 | COMPOSITIONS AND METHODS FOR PRESERVING RNA IN BIOLOGICAL SAMPLES - The present invention concerns methods and compositions to prepare biological samples to preserve the macromolecules in the samples. Embodiments of the invention concern the use of a soak solution that contains one or more water-miscible solvents. A sample is incubated with the soak solution to the point of saturation at a temperature above the melting temperature of the water-miscible solvent but below 0° C. The use of methods and compositions of the invention allow for subsequent preparation or analysis of the samples. | 08-06-2009 |
20100330695 | SAMPLE APPLICATORS FOR ANALYTICAL ASSAYS - A liquid applicator for applying a liquid sample to a liquid receiving surface is disclosed. The liquid applicator comprises a bibulous line to hold a first predetermined volume of liquid for application to a liquid receiving surface. A second predetermined volume less than or equal to the first predetermined volume is applied to the liquid receiving surface in a substantially uniform and consistent pattern. Systems and methods for using embodiments of the liquid applicators are also disclosed. | 12-30-2010 |
20120164748 | Nanoliter Array Loading - An interface is provided for storing microfluidic samples in a nanoliter sample chip. A fluid access structure provides a fluid access region to a selected subset of sample wells from an array of sample wells. A fluid introduction mechanism introduces a sample fluid to the fluid access region so that the sample wells in the selected subset are populated with the sample fluid without the unselected sample wells being populated with the sample fluid. | 06-28-2012 |
20120220046 | Method and apparatus for forming the doped cryo-biology specimen of electron microscope - The invention discloses a method and apparatus for forming the doped cryo-biology specimen of electron microscope.

20140134749 | SAMPLING PROCEDURE FOR POLYMER-BASED SOLUTIONS USED IN UNDERGROUND FORMATIONS - This invention concerns a sampling procedure for an aqueous hydrosoluble polymer solution flowing in a main circuit, enabling a sample to be collected to undergo at least one analysis under ambient air giving at least one property of the hydrosoluble polymer characterised in that a stabilizing solution is added to the aqueous hydrosoluble polymer solution, according to a discontinuous addition method, before or after sampling from the main circuit, so as to obtain a sample comprising a mixture of aqueous hydrosoluble polymer solution and stabilizing solution in which the hydrosoluble polymer is protected against attacks it may undergo in an atmosphere containing at least 10% by volume of oxygen. | 05-15-2014 |
20140342466 | Nanoporous substrates for analytical methods - Nanoporous materials can be used to enrich samples for subsequent analysis of substances contained in the sample. The method is shown to enrich the yield of species in the low molecular weight proteome, allowing detection of small peptides in the low nanomolar range. | 11-20-2014 |
20150056716 | Sample collection device - A sample collection device having a sample tube, funnel, and cap having a capsule and a piercing insert, the capsule having a stabilization solution. After depositing the sample into the tube via the funnel, the cap is screwed onto the tube, piercing the capsule and releasing the stabilization fluid into the tube. The device can be used at home without clinicial supervision for collecting a saliva sample and transporting the sample to an analysis location for DNA analysis. | 02-26-2015 |
20150093837 | Devices, Systems, and Methods for the Collection of Body Fluids - A method for the storage of biological samples is disclosed. The method includes the steps of coupling a storage device to a biological sample collection apparatus capable of collecting a biological sample from a subject, introducing a biological sample from the biological sample collection apparatus to the storage device, and drying the biological sample on the storage device. In another embodiment, the storage device used by the method may include a collection medium having a top surface, a bottom surface, and a predetermined size and shape, the top surface comprising a position marker and at least one binding site operable to bind a biological sample; and a protective facing substantially impermeable to the biological sample, the protective facing coupled to the top surface of the collection medium and having a size and shape substantially similar to the predetermined size and shape of the collection medium. | 04-02-2015 |
