Nonapeptide-1 /158563-45-2/GT Peptide/Peptide Supplier
Description
Melanogenic hormone (α-MSH) is a key signaling molecule in the process of melanin formation. It can be recognized and bound by the receptors on the melanocyte membrane, and has a wide range of stimulating effects on melanocytes. It can stimulate the division and proliferation of melanocytes, promote the expression of melanocyte tyrosinase, improve the activity of melanocyte tyrosinase, and increase the biosynthesis of melanin.
Nine-peptide-1 competitively blocks the receptors on melanocytes and the entrance of various factor signals, weakens the activity of melanocytes, reduces the amount of melanin production, and plays a uniform and brightening effect on skin color.

FAQ
Q:How to dissolve peptide?
A:Solubility may vary depending on the type of peptide. The most common solution is to dissolve 1mg of peptide in 1ml of distilled water.
Q:Why does peptide differ in solubility?
A:Solubility is important for using peptide. Each amino acid has its own chemical properties. For example, leucine, isoleucine, and valerine are hydrophobic, while other amino acids such as lysine, histidine, and arginine are hydrophilic. Therefore, different peptides have different solubility depending on their composition.
Q:What if the peptides don’t dissolve well?
A:In the usual method, the peptide must be dissolved in pure water. If dissolution is still a problem, try the following methods: Sonic degradation helps dissolve the peptides. Dilute solution with a small amount of acetic acid (10% concentration) helps dissolve general peptides, and aqueous solution with ammonia helps dissolve acidic peptides.
Q:What kind of report we provide along with peptide?
A:In my company, all peptides are subject to complete quality test, including HPLC, MS, Solubility. Special tests will be provides upon requests, such as Peptide Content, Bacterial Endotocins.
