Application Of Peptide Synthesis In Pipetting Service Center

Application of protein production in pipetting service center

Peptide synthesis is a complicated and important whole process common in analytical chemistry. In the whole process of peptide synthesis, several carbohydrates are connected by peptide bonds. Linking carbohydrates has been a common practice in analytical chemistry for many years, but the whole process has evolved. Technological development and more technical and professional production and processing technology enable scientific research staff to generate pure natural peptides, and create unique peptides with higher accuracy and reliability. As everyone knows, in order to respond to this question, "What is peptide generation", everyone must have a deep understanding of the diversity of the whole process and the operation of the program.

What is a peptide

First, you must have a basic grasp of peptides before you can correctly understand what peptides are produced. Peptides are made up of satchel carbohydrates, all of which are linked together by peptide bonds. Structurally, peptides and proteins are very similar, because they are all composed of carbohydrate chains, which are linked together by peptide bonds. As everyone knows, the key difference between peptides and proteins is their size. Proteins are generally composed of 50 or a large amount of carbohydrates, while peptides are generally located on the smaller side and consist of only 2 to 50 carbohydrates. In addition, the function of protein is slightly more complicated, and it can choose secondary, tertiary and four-level structure. Peptides show less genetic variation and are generally divided into only 2 subgroups. Oligopeptides are these peptides with fewer carbohydrates, generally in the middle of 2-20. Active peptides are these peptides with a lot of carbohydrates, when they are linked together, they will cause protein. Essentially, a protein is a large peptide composed of many active peptides.

Processing technology and process of peptide synthesis

Although peptides are found in all plants, the production of synthetic peptides is usually used by scientific researchers to produce special peptides. Very much, scientific research workers have generated these carbohydrates that are likely to be difficult to express in the bacteria or to carry out experiments on the fusion of carbohydrates that are difficult to detect in the active peptide. The common way to synthesize peptides is solid phase synthesis of peptides.

Solid phase peptide synthesis

Solid-phase peptide synthesis was innovated by the British microbial scientist Johnson Bruce Merrimand, and solid-phase peptide synthesis has become the core method of peptide synthesis. Solid-phase peptide synthesis, commonly known as "SPPS", simplifies the process of synthetic peptides based on several continuous carbohydrate reactions on a single porous structure device.

When the carboxyl group of the incoming carbohydrate is connected to the N-terminal end of the existing and growing peptide chain, peptide synthesis is produced. Carbohydrates are added to the growth and development peptide chains one at a time in a precise and circulatory method, and care must be taken to accurately follow the necessary procedures. The analysis staff must be very cautious when establishing this peptide chain. Since carbohydrates have several functional groups, they are likely to cause adverse reactions, thereby reducing the length of the chain or causing its branches. In order to reduce the probability of such adverse reactions, observation data analysts must use maintenance teams such as Fmoc or Boc. This kind of base unstable maintenance group and acid unstable maintenance group are each beneficial to complete the organic chemistry selectivity in the whole production process, and reasonably reduce the probability of all unexpected adverse reactions.

Once the system software is solved by this temporary maintenance base, it is relatively easy to add and remove this temporary maintenance base during the entire generation process, and carbohydrates can be added to the peptide chain. Carbodiimide is used to stimulate the C-terminal carboxyl group of carbohydrates so that it can be connected to the N-terminal of the growth and development peptide chain.

As you mentioned above, the whole process of "SPPS" is regular in order to achieve the required peptide bond length. This process has been repeated many times. Once the peptide bond is of the required length, it must be broken by all remaining maintainers. According to a whole process called acid hydrolysis, the peptide bond is detached from its remaining maintenance functional groups. In other words, the N-tail maintenance group of carbohydrates added later, the C-tail maintenance group of the first carbohydrate and all remaining main chain maintenance groups will be removed. The chemical product selected for this whole process will be the maintenance functional group applied in the system software. Acid-based maintenance teams, such as Boc, will have to apply strong bases, such as hydrogen bromide or hydrogen fluoride. Conversely, a softer acid (such as trifluoroacetic acid (TFA)) can be used to laser-cut alkali unstable maintenance groups, such as Fmoc.

Because SPPS is a relatively complicated whole process, it must be very careful and precise, so it is very likely to be very time-consuming. For this reason, many laboratories continue to use system software to simplify the steps. This kind of service center enables the observation data analyst to leave the system software unattended, and maintain sufficient confidence that the program flow will be carried out accurately and efficiently. The service center can accommodate larger samples and can carry out micro-manipulations based on electronic computers to obtain higher precision and precision.

HPLC peptide synthesis

Another technique of peptide synthesis is the synthesis of peptides in aqueous solution. Although the application is not very common, the technology has applied a lot of the same procedure as "SPPS". As everyone knows, this whole process is likely to consume a lot of time, because it stipulates to separate the substance peptide from the aqueous solution after each reaction process. Even more because of this, aqueous-phase peptide synthesis has been replaced by SPPS in many laboratories. Aqueous-phase peptide synthesis is still a common method in large-scale active peptide production, but it is generally used in industrial production.

Use of peptide synthesis

Peptide synthesis is generally combined with epitope mapping and is generally used in medicine and biotechnology. Synthetic peptides are used in scientific research for potential diagnosis and treatment and the development and design of drugs. When fused with epitope projection (epitope projection is the whole process of identifying the fusion domain in the synthesis of antigenic peptides between the two antigens), it can be used to generate antibodies and establish a more intelligent pre-vaccination design. Synthetic peptides can also be used for mass spectrometry analysis. In mass spectrometry analysis, they can be used as standard materials as well as experimental reagents.
