Catalogue number



Thymopentin, also known as TP-5, is a synthetic pentapeptide which is the active site of the naturally occurring hormone thymopoietin with immunomodulating properties (corresponding to the amino acids 32-36 of thymopoietin). Thymopentin enhances the production of thymic T cells and may help restore immunocompetence in immunosuppressed subjects. This agent also augments the effects of ionizing radiation by arresting cancer cells in the G2/M phase of the cell cycle.


Thymopentin has a molecular formula of C30H49N9O9, Arg-Lys-Asp-Val-Tyr-OH having an Mw of 679.8 Dalton.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.


The protein (1mg/ml) was lyophilized with no additives.


It is recommended to reconstitute the lyophilized Thymopentin in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized Thymopentin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TP-5 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.


Greater than 99.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
