Method and device for collecting and preserving cells for analysis
The claimed subject matter comprises a device to collect and preserve cells comprising of: (1) a collection container comprised of a tube having an open end and a closed end, a closure in the open end of the tube, a vacuum drawn to a predetermined level inside the container; and (2) compounds including an anticoagulant agent and a fixative agent, wherein the compounds are in a sufficient amount to preserve said cells” original morphology and antigenic sites without significant dilution of said cells, and thereby allowing said cells to be directly analyzed by a flow cytometer without further treatment. The claimed subject matter further comprises of a method of making a collection device for cells comprising of: (1) providing a tube having an open end and a closed end; (2) preloading compounds including: an anticoagulant agent, and a fixative agent into the tube, wherein the compounds are in a sufficient amount to preserve the cells” original morphology and antigenic sites without significant dilution of the cells, and thereby allowing the cells to be directly analyzed by a flow cytometer without further treatment; (3) inserting a closure into the open end of the tube; and (4) drawing a vacuum inside the tube to a predetermined level to form the collection device.
Kits for stabilizing analytes in urine samples
Disclosed here are kits comprising pre-packed stabilizing solutions for stabilizing combinations of biomarkers at room temperature. Such kits can be better adapted for sample collection at a subject's dwelling, thus easing the burdensome requirement of sample collection.
TESTING EQUIPMENT SYSTEM
A testing equipment system collects a specimen from a subject and measures the specimen, and includes a first unit portion forming a collection room including equipment to collect the specimen, a second unit portion forming a measurement room including equipment to measure the specimen, separately from the collection room, and a third unit portion including equipment to output a measurement result. The testing equipment system is placed at a moving base for passenger transportation.
MODULAR DRUG PRODUCTION SYSTEM
A portable system for producing a formulation comprising lipid nanoparticle (LNP)-encapsulated RNA includes: a first sub-system comprising multiple drug substance formulation modules, the first sub-system comprising: a transcription module for forming an RNA solution via in vitro transcription; and a second sub-system operatively downstream of the first sub-system comprising multiple drug product formation modules, the second sub-system comprising: an LNP formulation module for producing a first RNA-LNP preparation from the RNA solution, wherein each of the transcription module and the LNP formulation module is contained within a separate standard shipping container.
Method and apparatus to minimize diagnostic and other errors due to transposition of biological specimens among subjects
A method and apparatus for minimizing diagnostic errors due to transposition of biological specimens among subjects provides for independent biometric confirmation that a given specimen is from a given donor. In certain embodiments, a biological specimen confirmation kit comprises a portable and openable case housing components of the kit, at least one biological specimen container adapted to receive a biological testing specimen from a donor, and at least one reference sample device adapted to receive a biological reference specimen from the same donor, such that the testing and reference specimens can later be compared for donor match verification by a reference verification entity.

SAMPLING HOUSING AND MODULAR CONTROLLER COMPRISING THIS SAMPLING HOUSING
The present invention relates to a sampling housing and to a modular controller formed by this sampling housing when it is connected to a control station. This housing comprises a device supporting an assembly (3) consisting of a well plate (4), of a cap adapter (5) comprising as many orifices as there are wells and arranged on said well plate (4), and of caps (6), each cap (6) cooperating with a single well of the plate (4). The invention is applicable in the field of analyzing biological samples.
Portable nucleic acid extraction apparatus and method of using the same
A portable nucleic acid extraction kit includes a portable nucleic acid extraction apparatus, at least one lysis buffer, at least one binding buffer, at least one washing buffer, at least one elution buffer, and at least three kit sample tubes. The portable nucleic acid extraction apparatus includes a handle, a rod, a tip, and may include a nucleic acid binding medium. The method of using the portable nucleic acid extraction apparatus includes, treating a biological sample having a nucleic acid, binding the nucleic acid in the treated biological sample to the tip of the portable nucleic acid extraction apparatus, incubating the tip of the portable nucleic acid extraction apparatus bound with the nucleic acid, washing the tip of the portable nucleic acid apparatus bound with the nucleic acid, eluting the bound nucleic acid, and analyzing the eluted nucleic acid.
Monitored Mobile Personal Substance Testing System
A system for testing an individual for illicit or other substances is described. The system operates in tandem with a mobile device (smartphone) application, which employs a camera of the mobile device to capture and record the self-administered specimen collection process for verification and rule compliance. The system guides the user through the process via on-screen prompts on the mobile device, and includes tracking of the collected specimen from the moment of collection until it is sealed in a tamper-proof container to be mailed for external testing at a lab. A breathalyzer may also be used with the system to test for the presence of alcohol in the user's body, the use of which is also monitored and recorded via the on-board camera of the mobile device for verification.
FERTILIZER COMPOSITION AND METHOD FOR SUSPENDING FERTILIZER IN AN AQUEOUS SOLUTION
A system and method for providing fertilizer for crop production in an aqueous solution comprising nano-sized fertilizer particles, which are free of any chemical side chain and free any micelle to protect the nano-sized particle from re-agglomeration, suspended therein for improved uptake by the population of the crop.
