From the beginning of this year's solar term, the snow began to snow in the north, but the number of snowfalls was relatively small and the amount of snow was small. During the snow season, the temperature continued to drop, and the direct result was that the temperature in most areas of northern China gradually reached below 0°C, while many areas in the middle and lower reaches of the Yangtze River gradually entered the winter.
From the beginning of this climate, the northeast wind blows much. Since the climate hasn't cooled to the winter, many people don't pay much attention to wearing hats and scarves. "The head is the meeting of Zhu Yang", that is, the head is where all the Yang Jing gathers. The cold cannot be affected most. Everybody must wear a hat and must pay attention to cold protection and yang protection.
In this solar term, indoor heating starts to heat up, outside is cold, people wear it tightly, and the heat inside the body does not go out, it is easy to have an “inner fireâ€, which is what people often say is easy to get angry. I often hear people around the mouth have oral ulcers, and even more facial paralysis than usual, these are the performance of the internal fire, although people like to eat hot food on cold days, but Prof. Jiang warned everyone, too It is best not to eat spicy food, which will further promote the body's "inner fire." In addition, in a cold and dry room, most people feel that their noses and mouths are dry and they seem to have to use fire. It is recommended that you can drink hot soup, such as cabbage bean curd soup, spinach tofu soup, mutton white radish soup, etc., which is both warm and nourishing body fluids. . This season's cabbage and radish are seasonal foods, rich in vitamins and trace elements, and white radish can clear fire gas, digestion, is very suitable for consumption in this solar term.
Extraction Kit Magnetics Bead Method
This standard specifies the terms and definitions, classification, technical requirements, test methods, identification, labels and instructions for use, packaging, transportation and storage of nucleic acid extraction kits (magnetic beads method) (hereinafter referred to as "kits"). This standard It is suitable for extracting and purifying human genomic nucleic acid and its fragments from various clinical samples such as serum, plasma, whole blood, cerebrospinal fluid, milk, saliva, urine, sputum, swab, tissue or paraffin-embedded tissue by magnetic bead method , Pathogen nucleic acid kit. Pathogen nucleic acid includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), etc. This standard does not apply to nucleic acid extraction reagents contained in closed systems that cannot extract nucleic acid extraction products for detection.
This kit uses magnetic beads with unique separation function and a unique buffer system to separate and purify high-quality virus from serum, plasma, lymph, cell-free body fluid, cell culture supernatant, urine or various virus preservation solutions DNA/RNA. The uniquely embedded magnetic beads have a strong affinity for nucleic acids under certain conditions, and when the conditions change, the magnetic beads release the adsorbed nucleic acids, which can achieve the purpose of rapid separation and purification of nucleic acids. The whole process is safe and convenient, and the extracted viral DNA/RNA has high yield, high purity, stable and reliable quality, and is especially suitable for automated extraction of high-throughput workstations. The nucleic acid purified by this kit can be applied to various routine operations, including RT-PCR, fluorescence quantitative PCR and other downstream experiments.
