Purchase Nisin 1414-45-5

Nisin, also known as lactococcin, is a light brown solid powder that needs to be dissolved in water or liquid for use. Its solubility varies with different pH values, and it typically has a content of 99%, indicating high purity. Nisin is a product with well-defined characteristics and functions.

Nisin is a natural bioactive antimicrobial peptide extracted from Lactococcus lactis through biotechnology. It is a pure, natural, efficient, and safe polypeptide active substance composed of 34 amino acids, including five rare amino acids. These form five internal rings through thioether bonds, with active molecules often existing as dimers or tetramers.

Research has identified six types of Nisin: A, B, C, D, E, and Z. Among these, Nisin A and Nisin Z are the most actively studied. The difference between Nisin A and Nisin Z lies in the type of amino acid at the 27th position: Nisin A has histidine (His), while Nisin Z has asparagine (Asn). At the same concentration, Nisin Z has better solubility and stronger antibacterial properties than Nisin A.

In the food industry, Nisin is widely used as a preservative in meat, fish, dairy products, and other foods to extend shelf life and prevent bacterial growth. It is also used in the pharmaceutical industry. When using Nisin, one should first wash their hands and place the product in the palm. Then, follow the instructions on the medication leaflet to extract the required amount and apply it to the affected area. Avoid applying other medications simultaneously. After application, wash your hands and seal the product tightly to prevent moisture.

Nisin is a natural, efficient, and safe antimicrobial peptide with extensive industrial and medical applications.
