FAQ

How to dissolve peptide?

Solubility may vary depending on the type of peptide. The most common solution is to dissolve 1mg of peptide in 1ml of distilled water.

Why does peptide differ in solubility?

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.

What if the peptides don’t dissolve well?

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.

What kind of report we provide along with peptide?

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.

How to know your peptide purity?

The peptide purity appears in the COA, and please refer to the HPLC chromatogram.

If Peptide Content is 80%, what is for the other 20%?
Salt and water.

If the peptide is 98% pure, what is for the remaing 2%?
2% consists of unremoved impurities.

Does the several days international transportation will have effection on peptide?

The peptides that you will receive are freeze-dried powder and properly packed.

And usually the peptide powder can be kept at room temperature without damage.

Please freeze and store immediately upon receipt.

What else should we pay attention to during storage?

You received the peptide in a freeze-dried powder with proper pack.  Peptide is hydrophilic, absorption of water will reduce the stability of peptide, peptide content.

Please follow instructions as below:

First, use desiccant to keep the peptide in a dry environment.

Second, please keep the peptide in freezer at -20℃, in order to maintain maximum stability.

Third, avoid using the freezer without automatic frost function. Changes in humidity and temperature can affect the stability of the peptide.

Fourth, the external temperature in transport will not affect the expiry date and quality of the peptide.

How long will the peptide solution be kept?

It is not recommended to keep Peptide solution for a long period of time, and it’s recommended to prepare at the time you used it.

Is the solubility of the peptide related to the quality of the peptide?

It is difficult to accurately predict the solubility of a peptide and what the appropriate solvent is.

It is not true that there is a problem with peptide itself if it is difficult to dissolve.

What kind of peptide purity we provide?

≥99%, ≥98%, ≥95%, ≥90%, ≥85%, ≥80%, ≥75%,or crude.

What’s your suggestions on the design of phosphorylated peptides?

The synthesis direction is from the C to the N terminal. It is recommended that the residues after the phosphorylated amino acid should not exceed 10. That is, the number of amino acid residues before the phosphorylated amino acid from the N terminal to the C terminal should not exceed 10.

Which forms of salt can you provide ?

Default is TFA salt. We also provide Acetate, HCl, ammonium salt, sodium salt, phosphate salt , arginine salt, desalt form, etc. Salt exchange will be requested of an additional fee.
