FAQ：

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.

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 are the differences between peptides and proteins?

Peptides and proteins are both composed of amino acids, but they differ in molecular weight and length. Generally, those with a molecular weight less than 10,000 daltons (Da) and shorter amino acid chains are called peptides, while those with a larger molecular weight and longer amino acid chains are referred to as proteins.

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.
