Potential methods for peptide degradation
The chemical resistance of peptides depends on the composition and sequence of amino acids. Lyophilized peptides are generally more durable than their counterparts in solution. Potential degradation methods of peptides are as follows: 1, hydrolysis: this is usually included in the Asp in the sequ...Read more -
Antimicrobial peptides have a good inhibitory effect on Helicobacter pylori
Helicobacter pylori, or Hp, is a risk factor for gastric cancer with a high prevalence. It is the only bacteria that can survive in the stomach at present and can adapt well to strong acidic environment. About 56% of the population in our country is infected. In recent years, the high resistance ...Read more -
Peptide drugs open up a new opportunity in the field of anti-infection
In terms of the characteristics of peptide drugs, compared with monoclonal antibody drugs, recombinant protein drugs and small molecule drugs, peptide drugs have the advantages of simple spatial structure, obvious effect, high safety factor, wide application range and controllable quality. Theref...Read more -
Mezlocillin and its application were briefly described
Mezlocillin has a similar antimicrobial profile to piperacillin, with better activity against Enterobacteriaceae and less activity against Pseudomonas aeruginosa than oxacillin. It is used in medicine for respiratory tract infection and urinary tract infection caused by sensitive bacteria. Scope ...Read more -
What is the role of ninapepin-1?
Nonapeptide-1, as a whitening nonapeptide containing nine amino acids, plays an important role in whitening, brightening and fspotting. The role and effect of nonapeptide-1 is to inhibit the production of melanin, enhance the antioxidant capacity of the skin, alleviate the phenomenon of skin infl...Read more -
How can cross-linked mass spectrometry be used to analyze the structure of peptides in complex samples?
In the biomedical industry, peptide drugs have attracted much attention due to their high efficiency and low side effects. However, the complexity of the polypeptide structure is essential for a full understanding of its properties and function. As a powerful tool, cross-linked mass spectrometry ...Read more -
Further exploration of PeptideMassSpectrometry
PeptideMassSpectrometry is a powerful and widely used bioanalysis technology that brings scientists a window into the structure and function of living molecules.

Use of Abarelix Acetate
Overview Abarelix Acetate consists of ten amino acids that directly inhibit the metabolism of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and reduce the production of testosterone in the testis. Because of the direct inhibition of LH secretion, blood testosterone concentration...Read more -
Overview of Protein expression
proteinexpression refers to the technology of reproducing the target gene into an artificial vector and then introducing it into the recipient cell or cell-free system to express the protein in heterologous system. Protein expression can solve the problem that native proteins are difficult to obt...Read more -
An overview of disulfide bonds in chemistry and biology
Chemically, the disulfide bond refers to the R-S-S-R “functional group. Disulfide bonds usually consist of two thiol groups. In biology, disulfide bonds formed between thiol groups in two cysteine residues are an important part of the secondary and tertiary structure of proteins. This bond ...Read more -
