Abstract: Formulations for extraction and stabilization of G-Protein Coupled Receptors (GPCRs), kits and methods for their use for extracting GPCRs from biological specimens (e.g., cells and tissues), and methods for making such formulations in bulk scale are described. GPCRs extracted from cells and tissues using the described formulations remain in a functional, solubilized form over extended time periods.

Abstract: The present specification relates to compositions, devices, apparatus, methods, kits and systems for sample preparation (e.g., separation, reduction or removal of small molecules from biomolecules in a sample). Exemplary small molecules that can be separated, reduced or removed have a molecular weight range of <2000 Da. and may include, but are not limited to, dyes, biotin, affinity tags, crosslinkers, reducing agents, labels, nanoparticles, radioactive ligands, mass tags, unreacted molecules and combinations, intermediates and derivatives of the foregoing. Exemplary biomolecules present in a sample, include but are not limited to, proteins, glycoproteins, antibodies, peptides, nucleic acids, polysaccharides, carbohydrates and lipids. Methods, compositions, kits, devices, apparatus and systems of the disclosure may advantageously provide superior separation of small molecule contaminants and additionally reduce time and expenses related to separation of small molecules from larger biomolecules in samples.

Abstract: Devices and methods are described for a contrast tray and framing devices for use with imagers. Some embodiments describe a contrast tray for use with an imager comprising one or more light diffusing layers configured to shift at least some of an imaging light and one or more light filtering layers configured to filter out at least some of the imaging light. Light diffusing and light filtering layers can be further configured to upconvert at least some of the diffused and/or non-filtered light. Contrast trays can be used to improve imaging of gels such as PAGE gels when using a green or blue-green light. Other embodiments of the disclosure describe a framing device that provides better illumination and lower background fluorescence for fluorescent gels, such as nucleic acid gels.

Abstract: Dialysis devices include a frame defined by a plurality of sidewalls that are impermeable to a sample being dialyzed, a pair of dialysis membranes that are each associated with an opposing face of the plurality of sidewalls such that the plurality of sidewalls and the pair of dialysis membranes define a sample chamber, an outer shell surrounding at least a portion of the pair of dialysis membranes, and a cap selectively associated with the sample chamber. The cap can be selectively associated with the sample chamber via an attachment mechanism that is configured to provide aural and/or haptic feedback when the cap forms a tight association with the sample chamber. The cap can be a sensor cap having one or more probes for measuring at least one property of fluid inside and/or outside the sample chamber and a transmitter for transmitting data captured at the probe(s) to a destination device.

Abstract: A method for absolute protein or peptide quantitation by mass spectroscopy. A sample containing a protein or peptide of interest is prepared for mass spectroscopy analysis. The sample is subjected to mass spectroscopy analysis at low resolution whereby a single additive mass spectroscopy peak is obtained, then is subjected to high resolution mass spectroscopy analysis whereby a plurality of mass spectroscopy peaks are obtained. The intensity of each of the plurality of mass spectroscopy peaks is quantitated either by comparison to an internal standard set, or by using a standard curve generated for each isotopologue set. Quantitation using a standard curve enhances quantitation across a dynamic range of analyte.

Abstract: A method to maximize use of the field of view for an imaging system is provided herein. An imaging device can be part of the imaging system and include a detection unit and an alignment unit. The method includes capturing an initial image of an object and then calculating a rotational angle and zoom factor for the object in order to maximize the object's footprint within the field of view. Once the calculations are complete a computer can instruct the detection and alignment units to reconfigure their orientations relative to the object.
