FAQ：

What is net weight? What is peptide content?

After lyophilized peptide is generally fluffy and fluff-like, it may still contain trace amounts of water, adsorbed solvents and salts due to the characteristics of peptide itself. This does not mean that the purity of the peptide is not enough, but that the actual content of the peptide is reduced by 10% to 30%. The net weight of the peptide is the actual weight of the peptide minus the water and protonated ions. In order to ensure the concentration of peptide, the non-peptide substances need to be removed from the crude peptide.

Why should peptides be modified by N-terminal acetylation and C-terminal amidation?
Such modifications can give peptide sequences properties that are native to proteins.

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.

How do I store peptides?
Usually the peptide product you receive is lyophilized powder packaging, please store the peptide in a dry, dark -20°C freezer immediately after receiving the sample to maintain the peptide stability as much as possible. Before use, place the polypeptide packaging tube from the freezer to a dry condition at room temperature, and allow the temperature to naturally warm to room temperature before opening the cap. Otherwise, water vapor in the air will enter the sample tube when the lid is opened, reducing peptide stability. Once opened, it should be weighed quickly and immediately sealed to avoid deliquescent, and hydrophilic peptides should be more careful to avoid repeated freezing and thawing. Outside temperature during short-term transportation will not affect the shelf life and quality of peptides.

Which modified labeled polypeptides can be synthesized in Chinese peptide?

Our company provides a variety of modified peptide labeling, such as acetylation, biotin labeling, phosphorylation modification, fluorescence modification, can also be customized according to your special needs.
