Prostamax 20 mg

What is Prostamax?

Prostamax is the tetrapeptide Lys-Glu-Asp-Pro, formula C20H33N5O9, mass 487.5, CAS 473578-47-1, from the Khavinson bioregulator series, associated in that literature with prostate tissue models. The certificate's identity mass agrees with the formula. The published record is sparse and from one group, so the supplier and lot belong in the methods section. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.

What is Prostamax studied for?

• Prostate tissue research models
• Short-peptide bioregulator comparisons
• Tissue-specific gene expression studies
• Ageing-model research

All applications above are in-vitro or preclinical research contexts. Prostamax is sold for laboratory research only and is not for human or animal use.

What does the certificate for lot PROS20-0318 show?

Every lot of Prostamax is tested by an independent US laboratory before it is listed. The report for lot PROS20-0318 is in the COA library and the lot number printed on the vial matches it. The current results:

How is Prostamax handled and stored?

Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
