What peptide synthetic methods are used?
Fmoc and Boc methodologies are both employed, using solid and solution phase reactions.
How should I solubilise my peptide?
First try to dissolve a small amount of the peptide in either water or buffer. If the peptide does not dissolve try using an organic solvent such as DMSO to solubilise the peptide, then dilute using water or buffer.
Why do my products arrive at room temperature when the indicated storage temperature is +4°C or -20°C?
If the products are delivered at room temperature, it means they are stable during shipping and proper handling. Normally, storage in the refrigerator or freezer is only required for long-term storage and products in powder form can store up to 2 years at -20°C.
Do different batches of a product always look the same?
Occasionally, different batches of the product may look slightly different in color and appearance. But it will not affect purity, quality or performance of the product.
Why my product can hardly be seen in the vial?
Sometimes, product in small quantities can easily attach to the wall of vial, so the vial looks almost empty. Make sure the product is completely dissolved with the right solvent using vortex or sonication.
Is my order confidential?
Every peptide synthesis is kept confidential, and we are happy to sign a confidentiality agreement.
What are the best storage conditions?
1.Store at -20 ° C or in a dry environment
2.Avoid repeated freezing and thawing
3.Avoid storage in a liquid state (store the lyophilized power in smaller packages for convenient use)
4.If it has to be stored in a liquid state, it shall be dissolved with aseptic water under weakly acidic condition and stored at -20℃.
What’s difference between polypeptide content and polypeptide purity?
A polypeptide product includes polypeptide itself, water and impurities such as organic salt introduced in the production process. The purity of the polypeptide refers only to the content of the peptide and the impurities, excluding water; while the content of polypeptide refers to the net content of the target polypeptide in the product, which is generally detected by N-element analysis or amino acid molecule; therefore, even if the purity of a polypeptide reaches 99%, its content may be only 70-80% because of the existence of water, organic salt, etc.
