Definitions
- the present invention relates to an anal light inspection apparatus and an anal light inspection method.
- a sample collected from a human body or an animal body is purified in a laboratory and a predetermined test is performed.
- the sample is subjected to pretreatment and purification through chemical and physical methods using a predetermined device, and the purified sample is finally collected as an analyte to perform a predetermined inspection.
- an analyte test apparatus and method and an analyte test system for detecting various biological components such as cells, proteins, and nucleic acids include a nucleic acid purification apparatus, a purification method, and a purified nucleic acid test system.
- Nucleic acid purification and detection technology is an essential technology widely used in genetic engineering and molecular biology, and has been widely used for biotechnology research, medical, and industrial purposes. This technology has been utilized in a wide variety of fields, such as microbial infection detection, biomarker detection, gene sequence detection, and mutant gene detection, and is an essential element for gene-based diagnosis.
- Nucleic acid purification is traditionally performed by dissolving biological materials through chemical and physical methods using ultrasonic waves, heat, proteinases, alcohols, and special reagents, followed by positively charged ion exchange resins or magnetic particles. by selectively binding nucleic acids to In this process, the researcher has to exchange the solution in each step of lysis, binding, washing, and elution.
- the purified nucleic acid should be transferred to a tube or well plate, which is a separate detection container for detection, and then mixed with an enzyme reaction solution for the nucleic acid amplification reaction in the corresponding container.
- Purification and detection of nucleic acids can be completed only when the detection vessel is transferred to equipment for reaction and detection such as nucleic acid amplification. This process inevitably involves a number of complex pipetting and sequential mixing, stirring, and transfer of different reaction solutions.
- these methods generally require a lot of time and labor to be performed in a laboratory.
- the process is performed using an automated robot, which requires a lot of space and cost investment.
- the equipment is operated when a certain number of samples are prepared, there is a disadvantage in that the inspection time for a small number of samples is delayed. Such an examination system is not particularly applicable to medical fields requiring rapid diagnostic results.
- Analyte test apparatus for purifying samples and collecting quantitatively as analytes, for point-of-care testing (POCT)
- the manpower required for the purification process must be minimized, and a predetermined solution for purification is required. It must be filled, and its small size must ensure mobility.
- POCT point-of-care testing
- one-time use must be secured, and it needs to be implemented as a low-cost device, but research on an analyte inspection device that perfectly satisfies these conditions and a method using the same is still insufficient. to be.
- Embodiments of the present invention were invented with the above background in mind, and an object of the present invention is to provide an analyte inspection apparatus capable of purifying the analyte of a sample and inspecting the refined analyte through a single device.
- an object of the present invention to provide an analyte inspection apparatus capable of cost-effectively inspecting a sample because the apparatus is miniaturized and the cost is low.
