South Korea develops new medical biochips Korean scientists announced on the 2nd that they have developed a new medical biochip. With this biochip, doctors can use a small amount of blood to more accurately identify the disease.
Jin Zhaoyuan, a professor of chemistry at Dongguk University in South Korea, who led the study, said that the biochip is used to analyze proteins in living organisms. Experiments show that this new biochip is superior in performance and sensitivity to existing products. Accuracy and sensitivity are two important factors in determining whether a person is infected with a disease. It has been reported that existing biochips of the same type, for example, measuring HIV (AIDS) causing AIDS, can produce erroneous results.
This new biochip will enable doctors to identify diseases with "very small" blood samples. This will help develop a variety of portable medical devices to facilitate personal inspection of your health in a timely manner. ——Shanghai Medical Device Industry Association website
Goji Polysaccharides is a rare plant polysaccharides containing protein, which have side chains of polysaccharide composed by six carbon sugars (rhamnose, arabinose, xylose, mannose, galactose, glucose) and main chains of protein composed by 18 kinds of amino acids. The glycoproteins with biological activity is a high-strength immune enhancer.
Wolfberry products with stable quality are all natural, safe, sanitary and fast absorption.Lycium barbarum polysaccharide extraction and purification is divided into two steps. First, the extraction of Chinese wolfberry crude polysaccharides, the second is purified Lycium barbarum polysaccharide. Crude polysaccharides extraction process is as follows: Weigh dried crushed medlar, petroleum ether: acetone (1: 1) reflux degreasing, the solvent was filtered off, the residue was air-dried 80% ethanol off monosaccharide and oligosaccharides.
The polysaccharide is extracted by water after dissolving the residues such as oligosaccharides in water at 90-100 DEG C, the extract is concentrated under reduced pressure, the polysaccharides are precipitated by ethanol, the precipitates are washed with anhydrous ethanol and acetone, and the lycium polysaccharides are dried under vacuum. The crude polysaccharide is purified by passing the Lycium barbarum polysaccharide through a column of DEAE cellulose with different concentrations of NaCl as an eluent, concentrating the eluates with different salt concentrations respectively under reduced pressure, desalting them by dialysis, and then lyophilizing them differently Grape Lycium glycoprotein.
Modern medical research suggests that wolfberry polysaccharides can improve human immunity and have functions as anti-cancer, cancer treatment, hematopoiesis, liver protection and hypotensive, free radicals removal , anti-fatigue, anti-radiation, and cell activity improvement; Goji polysaccharides can control cells division& differentiation, and regulate cell growth & aging, which is widely used in the pharmaceutical, health food and other fields.
