Preparation and detection reagent card case for nucleic acid or protein

Abstract

A preparation and detection reagent card case for nucleic acid or protein includes a case body provided with an open-close-type object placing opening and an open-close-type object taking opening. An extraction reaction chamber, an extraction reagent storage chamber, a cleaning chamber, an elution chamber and a detection reaction chamber are formed in the case body. The cleaning chamber is arranged between the extraction reaction chamber and the elution chamber, and solid transfer mechanisms are arranged on two ends of the cleaning chamber and are respectively connected to the extraction reaction chamber and the elution chamber adjacently. The solid transfer mechanisms serve as separation bodies for adjacent chambers when being idle and form paths between the adjacent chambers when being occupied to provide oriented magnetic force for transfer of the solid material. Through the solid transfer mechanisms having an individual structure, magnetic solid materials are transferred step-by-step among the chambers, so that the whole structure of the card case is greatly simplified. The card case integrates preparation and detection of the nucleic acid or protein, overcomes the problems that the extraction, detection and connecting steps therebetween have complex operations and samples or reagents are liable to be polluted.

Description

technical field [0001] The invention relates to consumables used in the preparation and detection of nucleic acid or protein, in particular to a nucleic acid or protein preparation and detection reagent cartridge. Background technique [0002] In the past, disease detection was mainly based on medical history, symptoms, signs and various auxiliary examinations, such as biochemistry, hematology, pathology, immunology, microbiology, etc. However, due to the limitations of the above-mentioned inspection methods, many diseases cannot be detected timely and accurately, which delays the opportunity of treatment. [0003] Today, with the transformation of the medical model and the continuous development of individualized medicine, the medical testing community urgently needs fast and accurate detection methods, and molecular detection has unique advantages. [0004] The basis of molecular detection is to analyze the genes and their expression products in the tissue cells, hair, an...
