Pentapeptide-18 /64963-01-5/GT Peptide/Peptide Supplier
Description
(D-ALA2) -leucine enkephalin is widely distributed in human body and has extremely important physiological functions. Not only has a unique effect on brain cells, can activate the sleeping state of brain cells, due to brain damage caused by sequelae have a good recovery effect; It plays an important Chemicalbook role in immune function, including increasing the activity of immune system, T lymphocytes, NK cells, macrophages, antiviral, and increasing the release of γ-interferon. The way in which the activated immune cells promote secretion of endocrine cells is involved in immune regulation, thus affecting the gene regulation and expression function of DNA

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.
