FAQ：

How is my peptide transported? What test reports are provided?

All freeze-dried polypeptides are usually stored in special containers of 2 ml or 10ml with original analytical data and synthesis reports containing important information such as sequence, molecular weight, purity, weight, and number of the polypeptide.

How pure can the peptide be?

Our company can provide different purity levels for customers to choose from, from crude to > 99.9% purity. According to customer needs we can provide purity > 99.9% ultra-pure polypeptide.

What is the direction of synthesis of peptides?
Peptide synthesis is from the C-terminus to the N-terminus of the polypeptide.

What length of peptide is appropriate?
Peptide synthesis needs to consider factors such as the length, charge, and hydrophilicity of the peptide. The longer the length, the purity and yield of the crude synthetic product decrease, and the difficulty of purification and the chance of non-synthesis will be greater. Of course, the sequence of the functional region of the polypeptide cannot be changed, but for the smooth synthesis of the polypeptide, sometimes some auxiliary amino acids have to be added to the upstream and downstream of the functional take to improve the solubility and hydrophilicity of the polypeptide. If the polypeptide is too short, there may also be problems with synthesis, the main problem is that the synthetic polypeptide has a certain difficulty in the post-processing process, and the polypeptide below 5 peptides generally has hydrophobic amino acids, otherwise the post-processing is more difficult. Peptides below 15 amino acid residues generally have satisfactory yields and yields.
