FAQ：

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.

What are peptides? 

Peptides are short chain molecules formed by amino acids linked together by peptide bonds. They

typically consist of 2 to 70 amino acids.

Were the peptides containing Cys reduced before shipment?

If the peptide is not found to have been oxidized, we generally do not reduce Cys. All polypeptides are obtained from crude products purified and lyophilized under pH2 conditions, which at least to some extent prevent the oxidation of Cys. Peptides containing Cys are purified at pH2 unless there is a specific reason to purify at pH6.8. If purification is performed at pH6.8, the purified product must be treated with acid immediately to prevent oxidation. In the final quality control step, for the peptides containing Cys, if the presence of molecular weight (2P+H) substance is found on the MS map, it indicates that a dimer has been formed. If there is no problem with MS and HPLC, we will directly lyophilize and ship the goods without any further processing. It should be noted that peptides containing Cys undergo slow oxidation over time, and the degree of oxidation depends on peptide sequence and storage conditions.

If you want to do a biotin modification at the N terminal, do you need to put a gap between the biotin and the peptide sequence?

The standard biotin labeling procedure used by our company is to attach an Ahx to the peptide chain, followed by biotin. Ahx is a 6-carbon compound that acts as a barrier between the peptide and the biotin.
