Synthesis of anti COVID-19 polypeptide | polypeptide customization

Peptide vaccines are vaccines prepared by chemical synthesis techniques based on the amino acid sequence of a known or predicted antigenic epitope in the pathogen antigen gene.

Traditional vaccines are generally prepared in two ways: one is attenuated vaccines that can induce immunity but do not cause disease, such as yellow fever, poliomyelitis, measles vaccines or BCG vaccines; Another type is inactivated vaccines (such as pertussis bacilli, rabies virus, typhoid bacilli). Peptide vaccines, due to their complete synthesis, do not have the problem of toxicity rebound or incomplete inactivation. Especially for some microbial pathogens that cannot obtain sufficient amounts of antigens through in vitro culture.

Compared with attenuated and inactivated vaccines, viral antigen epitope peptide vaccines have the following advantages:

1) More suitable for dealing with virus mutations;

2) Can meet the requirements of fast and efficient production, and reduce the cost of vaccine production;

3) The vaccine lacks a complete viral structure and has a high level of safety.

Advantages of company peptide synthesis:

Good quality: For long and short peptides, liquid-phase peptide synthesis and solid-phase peptide synthesis processes are adopted to synthesize peptides, and HPLC is used to purify the products. The final product provides corresponding mass spectra, HPLC chromatograms for purity analysis, and COA.

Fast delivery: The ordering process is simple, the peptide synthesis production process is carried out in shifts, the delivery process is smooth, and the confirmation of payment process is convenient and fast. We can deliver the finished product for use as soon as possible, reducing intermediate links.

Confidentiality: We will strictly keep confidential the peptide synthesis sequences provided by our customers and will never disclose them.
