Description：Prostamax is a prostate-targeted active peptide. Its core functions include inhibiting abnormal proliferation of prostate cells, exerting anti-inflammatory and antioxidant effects, and promoting tissue repair and chromatin decondensation. It is widely used in preclinical studies of benign prostatic hyperplasia, chronic prostatitis, prostate cancer, immune senescence, and tissue regeneration.

FAQ：
How do you dissolve polypeptides?
The solubility of polypeptide depends mainly on its primary and secondary structure, the nature of modification label, solvent type and final concentration. If the peptide is insoluble in water, ultrasound can help dissolve it. For basic peptide, it is recommended to dissolve with 10% acetic acid; For acidic peptides, dissolution with 10%NH4HCO3 is recommended. Organic solvents can also be added to insoluble polypeptides. The peptide is dissolved in the least amount of organic solvent (e.g., DMSO, DMF, isopropyl alcohol, methanol, etc.). It is highly recommended that the peptide be dissolved in the organic solvent first and then slowly added to water or other buffer until the desired concentration.
I need a cyclic peptide, which contains a tryptophan, will it be oxidized?
The oxidation of tryptophan is a common phenomenon in peptide oxidation, and peptides are usually cyclized before purification. If the oxidation of tryptophan occurs, the retention time of the peptide on the HPLC column will change, and the oxidation can be removed by purification. Furthermore, oxidized peptides can also be detected by MS.
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 Prostamax is 98% pure, what is 2%?
Two percent of the composition was truncated or deleted sequence fragments.
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.
