The RNA purification kit is used to purify and recover RNA molecules transcribed in vitro and total RNA extracted from various materials, which can effectively remove contaminating impurities in RNA samples. The recovery rate of this product can reach 80%, and the OD260/OD280 ratio of the obtained RNA is generally about 2.0, which can be directly used in subsequent sensitive experiments (such as microarray analysis, fluorescence RT-PCR, etc.). With the deepening of transcriptomics, the complexity of RNA types, expression regulation and functions is far beyond our imagination.

February 28, according to foreign media reports, King's College London researcher Roger Ribas Manero announced that his team has developed wearable exercise equipment that can detect muscle fatigue. This smart leggings can detect muscle fatigue during exercise and has reached a practical level without a static experimental demonstration.
Currently, wearable equipment is gradually changing the way people think about lifestyle. Smart watches are changing the way people communicate, trajectory tracking is changing the way people exercise, and wearable cameras are changing the way people remember. A new generation of wearable devices provides a new way to detect human motion.
It is reported that muscle fatigue testing has always been a problem. The most sensitive method at present is to detect the bioelectrical signals of muscle nerves by inserting fine metal needles into the muscles to determine muscle fatigue. In addition, bioelectricity of the subcutaneous nerve can also be detected by providing an electrode on the skin. This method is simpler than the former, but the electrodes must be placed with caution and are difficult for people who have not received systematic medical training.
The equipment used in the above two methods is expensive and difficult to implement outside the laboratory, and is not suitable for the general public. The testing equipment developed by Ma Nylon and his team is now cheaper and more flexible. The device embroids electrodes in the tights and circuitry connected to the portable Arduino microprocessor to perform muscle fatigue analysis by collecting electrical stimulation data. The detection circuit adopts a Z-shaped serrated double-slit method to facilitate the stretching and stretching during exercise. In addition, the equipment is equipped with a 7.5V rechargeable battery. The double-slit mode of the sweatpants ensures that the electrodes are placed in the correct detection position of the human body, and the entire detection circuit is inexpensive and easy to produce, so that it is easy for the user to wear and use. The research team tested the status of the two athletes. The test recorded the athlete's muscle fatigue in three environments: road, track and field and beach. The test data shows how the athlete's leg muscles start to work hard, and fatigue begins after one or two minutes. This is the first time that a similar muscle fatigue test was conducted outdoors. In the future, this may change the way athletes analyze their own state of motion.
Muscle fatigue can easily cause unnecessary damage to athletes. This convenient detection method can effectively prevent the occurrence of sports injuries. According to Ma Nylon, “The data shows that exercise on the beach is more likely to cause sports injuries due to muscle fatigue than on roads and sports fields.†In addition, research on how muscles work can help prosthetic design and bipedal Research on the needs of robots.
In short, this device allows the athlete to not only understand the amount of exercise, but also to detect muscle strength and fatigue, thus opening up a new space for smart wearable devices.
Removing ribosomal RNAs that account for more than 80% helps to focus sequencing on less abundant but informative RNAs. At present, the removal of rRNA is mainly through the combined use of probe and RNase H. The processed RNA will be mixed with many digestion products, enzymes and ions, which is not conducive to the subsequent construction of RNA library. Take the Columnar RNA Purification Kit as an example. Trizol is a ready-to-use reagent that can be used to purify total RNA from tissues and cells. This is a single-phase solution of phenol and guanidine isothiocyanate that facilitates lysis of tissues and cells, inhibiting RNases to maintain RNA integrity.
