Description：Unlike traditional chemotherapeutic drugs that tend to damage normal cells, the core advantage of PNC-27 lies in "precision recognition". Studies have shown that it exerts its effect by targeting the HDM-2 protein, a molecule specifically overexpressed on the membrane of various cancer cells but barely detectable on normal cell membranes.

FAQ：

How do you determine if a peptide is looped?

We use the Ellman reaction to test whether the ring formation is complete. If the Ellman test is positive (yellow), the ring reaction is incomplete. If the test results are negative (not yellow), the ring reaction has been complete. We do not provide the analysis report of cyclization identification for our clients. Generally, there will be a description of Ellman's test results in the QC report.

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.

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.

If a PNC-27 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.
