Special Antigen Peptides Services
Peptide antigen, namely, a peptide used to trigger animal's immune system to develop antibodies specific to that peptide. Nowadays, the use of synthetic peptide antigens as immunogens has markedly increased, and this technique is also widely applied for immune research such as tumor immunotherapy etc. With ten years experience in antigen peptides supply, Creative Peptides is experienced in the synthesis of complex antigen peptides, such as glycopeptides or hyperphosphorylation peptides.
Although many peptide sequences are immunogenic, not all of them are identically effective in generating antibodies when act against the target protein. Effective antibody generation depends on several factors that need to be considered at the very first stage of peptides designing.
Mimicking specific parts of the target protein, peptide antigens can provide much flexibility for scientific research. However, most of synthetic peptides are composed of 10AA -25 AA, which are too short to generate a strong immune response without prior conjugation to a carrier protein such as Keyhole Limpet Hemocyanin(KLH), Ovalbumin(OVA) or Thyroglobulin(Tg). Creative peptides specialists can help with antigen design to maximize the chances that the peptide used as antigen can generate sufficient and effective antibody.
