Have you ever had such an experience... At the end of the research work, the magazine you submitted for is required to provide a report on the cell STR. At this time, whether the cells used in your research are contaminated will determine the success or failure of your research work for several months or even years. Have you ever had such an experience... Are the newly purchased cells, the cells that have been passed down for generations in the laboratory, or the cells that have been stored in the ultra-low temperature refrigerator for several years, are contaminated? Is the identification correct? Does research with it affect the results of the experiment? Without the corresponding cell identification, the contaminated cells were used, and after a large number of experiments, a paper was written, but the conclusion was overthrown, the paper was recalled, a lot of time, material and manpower was wasted, and everything had to start all over again. If you are a student waiting to graduate, waiting for you will be postponed. Misidentification of cell lines not only wastes time and money, results in inconsistent or inconsistent results, and the literature is returned, potentially posing a potential threat to human health. Drugs, vaccines, and other biopharmaceuticals are based on laboratory findings and are often associated with cell culture. Drug products made based on misleading or false data will delay the full production of the drug, while delaying the introduction of effective treatments for multiple diseases. The longer you develop treatments, the more people will suffer from the disease. Choosing the right cell is half the success of the experiment. Cells are a very special commodity. Because of their reproducibility, they are easily copied and sold by some merchants. These self-passing and replicating cells have almost no cost, so it is easy for everyone to buy. However, the number of times these cells were passaged, the conditions of culture, and whether there was any pollution were not guaranteed. Even the teachers bought the cells and did a lot of experiments without any results. It was only after a long time that the cells were found to be contaminated. In order to relieve your worries, we recommend that you perform STR identification on your cells at the beginning of the cell line, after a period of cell passage, and immediately before the publication of the paper. To make sure you use the correctness of the cells. Using the right cells is half the success of your experiment. Original link http://?id=320 Remarks: This article was published by Xiaobian.

Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
