El ADN, como portador de información genética y la base material de la expresión génica, juega un papel extremadamente importante en el crecimiento, el desarrollo, el envejecimiento, la genética y la mutación del organismo.

DNA, as the carrier of genetic information and the material foundation of gene expression, plays an extremely important role in the growth, development, aging, genetic, and mutation of the organism.

Los biomarcadores de tinte fluorescente orgánico y las sondas fluorescentes moleculares tienen las ventajas de una operación simple y una buena reproducibilidad.

Organic fluorescent dye biomarkers and molecular fluorescent probes have the advantages of simple operation and good reproducibility.

El sistema de color de cabello de los tintes/pigmentos sintéticos es un sistema electrónico común. Estos sistemas no solo producen colores, sino que también tienen muchas otras funciones relacionadas con las funciones de luz, calor, eléctrica, química, bioquímica y otras funciones. Estos colorantes

El tinte de azufre tiene una historia de más de 100 años desde su nacimiento. El primer tinte de azufre fue hecho por Croissant y Bretonniere en 1873. Contendrán fibras orgánicas, como chips de madera, salvado, algodón y desechos. Papel y otros sulfuro y otro Se obtienen álcali polisulfonal.

Sulfur dye has a history of more than 100 years since its birth. The first sulfur dye was made by Croissant and Bretonniere in 1873. They will contain organic fibers, such as wood chips, bran, scrap cotton and waste. Paper and other sulfide and polysulfonal alkali are obtained.

The three -color lace elastic fabric developed by the four types of fiber -developed fiber development of an artificial silk, nylon, modified polyester filament, and Laica. According to the dyeing performance and characteristics of the fiber, the dyeing process includes water washing oil.

The emergence of disperse dye -alkaline dyeing:When decentralized dye dyeing conventional polyester, the general dyeing bath is generally controlled (pH value is 5-6). Due to dyeing under acidic conditions, most of the scattered dye color light is the purest and high -dye rate. However, polyester si

Cold -rolled pile staining, usually ethylene dyes. This is because the active base of the ethylene -type active dye is commonly used, which is very sensitive to alkali. In an alkaline bath, the reaction can be quickly disappeared, and the ethylene radon (-so2ch = CH2) with strong chemical activity c

pHFor active dyeing, when the pH value is 7 ~ 9, the color difference between the product is normal, indicating that the pH range has little effect on the product color difference, and the presence of a small amount of alkali will not change or destroy the active dye molecules.When the pH value is 8

HardnessIt is generally believed that the hardness below 50 ppm has no impact, and 20ppm is already a good water.The water quality of the tube yarn is not the same, but the copper and iron ion content in the water should be paid attention.Usually active dyeing is better below 50ppm. The key is the m
