FAQ：

Which end is best for my research?

By default, the peptide ends with an N-terminal free amino group and a C-terminal free carboxyl group. The peptide sequence often represents the sequence of the mother protein. In order to be closer to the mother protein, the end of the peptide often needs to be closed, that is, n-terminal acetylation and C-terminal amidation. This modification avoids the introduction of excess charge, and also makes it more able to prevent exonucliase action, so that the peptide is more stable.

What are the uses of peptides?

Peptides have a wide range of applications in the biomedical field, including:

Drug development: Peptides can be used as lead compounds for drugs or directly as drugs themselves.

Vaccines: Peptides can be used as antigens for vaccine preparation.

Biomaterials: Peptides can be used to construct biomaterials, such as scaffolds for tissue engineering.

Diagnostic reagents: Peptides can be used in the development of diagnostic reagents, such as those for detecting disease-related proteins.

Cosmetics: Certain peptides have moisturizing, anti-aging, and whitening effects and can be added to cosmetics.

Are polypeptides harmful to humans?

Peptides, which are naturally present in the human body, are generally safe for use. However, some peptides may have specific pharmacological activities, and it is advisable to consult with a doctor or a professional before using them.

What are the advantages of PEG-modified peptides?
Polyethylene glycol modification is the addition of a polymer (ethylene glycol) to the target molecule by means of covalent bonding. By camouflaging the peptide, the PEG modification fools the host cell's immune system, enhances the therapeutic effect of the peptide, and increases the solubility and bioavailability of the hydrophobic drug. It can also prolong the circulation time of polypeptides by decreasing renal clearance.

What do I need to look for when designing phosphorylated peptides?

When designing phosphorylation modifications, the phosphorylation modifications should not be more than 10 amino acids away from the N-terminus to avoid a decrease in coupling efficiency.
