What Is Solid Phase Synthesis Peptide?

Polypeptide synthesis on a solid support, a concept of originality pioneered by Robert Bruce M Merrifield in 1963, is a major breakthrough in peptide chemistry. 
  • In solid phase synthesis, it is conventional to assemble peptide chains starting from the C-terminus.
  • First, a linker is introduced on the polymer carrier; then, the N-terminal protected amino acid reacts with the functional group of the linker;
  • then the temporary protecting group is removed and condensed with the next amino acid, and this step is repeated until synthesis is required The sequence;
  • finally, cleaves the covalent bond between the tether and the peptide chain, and removes the insoluble carrier from the dissolved product.


 The solid phase synthesis method effectively avoids the cumbersome and time-consuming separation and purification steps necessary for liquid phase synthesis, and has remarkable advantages, and its application value is irreplaceable.

Ion Exchange Resin for Water Softening, Demineralization, Harmful Ion Removal Drinking water, also known as potable water, is water that is safe to drink or to use for food preparation. Globally, by 2015, 89% of people had access to water from a source that is suitable for drinking - called improved water source. Agriculture is by far the largest water use at global level. Irrigation of agricultural lands accounted for 70% of the water used worldwide.The water quality used for irrigation is essential for the yield and quantity of crops, maintenance of soil productivity, and protection of the environment. For example, the physical and mechanical properties of the soil, ex. soil structure (stability of aggregates) and permeability, are very sensitive to the type of exchangeable ions present in irrigation waters. There are many uses of water in industry and, in most cases, the used water also needs treatment to render it fit for re-use or disposal. Raw water entering an industrial...

Resins Change The Old Materials Of The Past

When it comes to resin cotton, there are still many people who don't know what it is. In fact, there are many other names, such as non-rubber cotton, hot air cotton, Khmer elastic cotton and so on. The main components of resin cotton are polyester fibers and 4080 low melting point fibers. In the production process, 4080 low melting point fibers are used instead of adhesives, and the combing and netting technology is adopted. The product has good elasticity. The research and development of China resin manufacturers  has always been a professional level. Environmental friendly resin cotton has many characteristics. Because resin cotton has the characteristics of environmental protection, good elasticity and tasteless .   S unresin , one of China resin manufacturers seize the business opportunities, so it is widely used, such as sofas, mattresses, outdoor furniture, baby carriages, tatami and other software filling common in life can be used. The main application fields ...

How Does Ion Exchange Column Work?

Image
When the operation is carried out for a certain period of time, the resin bed will be divided into a saturated resin zone, a mass transfer zone, and a fresh resin zone. As the run time increases, the mass transfer zone gradually decreases until the bottom of the bed is penetrated by the mass transfer zone and the entire resin layer fails. For one application, the  fixed bed system  is usually operated in single column or two columns in series, plus a column for regeneration.
