FAQ：
Which modified labeled polypeptides can be synthesized in Chinese peptide?
Our company provides a variety of modified peptide labeling, such as acetylation, biotin labeling, phosphorylation modification, fluorescence modification, can also be customized according to your special needs.
What problems should be paid attention to in the storage process?
The peptide you received was packaged in lyophilized powder. Peptides are hydrophilic, and absorption of water will reduce the stability of the peptide and reduce the peptide content. Please pay attention to the following: first, with desiccants, stored in a dry environment. Second, once received, please immediately put into the freezer -20℃ storage, in order to maintain maximum stability. Third, avoid the use of no automatic frost function of the freezer. Changes in humidity and temperature can affect the stability of peptides. Fourth, the external temperature during transportation does not affect the validity and quality of peptides.
Can you give some advice on the design of phosphorylated peptides?
As the length increases, the binding efficiency gradually decreases from the phosphorylated amino acid onwards. The synthesis direction is from the C terminal 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.
If a Tb Frag 17-23 is 98% pure, what is 2%?
Two percent of the composition was truncated or deleted sequence fragments.
Is it necessary to put a gap between the peptide and the dye?
If you are going to attach a large molecule (such as a dye) to the peptide, it is best to put a space between the peptide and the ligand to minimize interference with the receptor by the folding of the peptide itself or by the folding of its conjugate. Others do not want intervals. For example, in the folding of proteins, it is possible to determine how far apart the folding structure of an amino acid is by attaching a fluorescent dye to a particular site.
