Vasopressin Impurities Synthesis

Vasopressin (AVP), also known as vasopressin and antidiuretic hormone, is a cyclic peptide hormone produced by neurons in the supraoptic nucleus of the hypothalamus. The related substances of synthetic peptides are mainly: process impurities brought in during the synthesis of vasopressin, such as peptide related substances such as missing peptides, broken peptides, oxidized peptides, etc; Degradation products and polymers produced by peptide deamidation, oxidation, hydrolysis, disulfide bond mismatch, racemization and other unstable factors.

With the development of chromatographic technology, impurity analysis has become the mainstream of drug quality control, and pharmacopoeias of various countries have issued impurity control guidelines.Then, the impurities in chemicals are controlled through "known impurities", "single unknown impurities" and "total impurities".Omizzur custom made Vasopressin API & impurities and welcome to inquiry.

Hot Vasopressin impurities：

• Endo-Gly9a-Vasopressin

• N-Acetyl Vasopressin

• Des-Gly-Vasopressin

• [D-Gln]Vasopressi

• [β-Asp]Vasopressin

It is valid for at least one year if stored at -20 ℃ or lower. Since each freezing and thawing of polypeptide will cause partial inactivation, after the storage solution with corresponding concentration is prepared for the first time (please prepare the storage solution according to the information in the column of reconstitution in the product introduction), it must be frozen at -20 ℃ or lower after sub packaging to avoid repeated freezing and thawing.

Shipping: By air or FedEx Express, delivery time: 5-10 days

Matters Needing Attention:

This product is freeze-dried powder. Since a small amount of polypeptide is deposited in the tube during the freeze-drying process, forming a very thin or invisible polypeptide layer, before opening the tube cover, we recommend centrifuging about 8000-12000g in a centrifuge for 10-30 seconds to make the polypeptide attached to the tube cover or tube wall gather at the bottom of the tube.

This product is only used for scientific research by professionals, and shall not be used for clinical diagnosis or treatment, food or drugs, or stored in ordinary houses.

For your safety and health, please wear lab clothes and disposable gloves.
