The stability of this material at -80°C has not been determined. In solid form, compounds are generally less sensitive to temperature, particularly for relatively short periods of time. It is likely that the quality has not been impacted. However this cannot be guaranteed. It would be up to the end user to determine the suitability for use.

General description
A potent competitive inhibitor of cytidine deaminase. Used in combination with cytosine arabinoside (Ara-C) to assess the anti-leukemic activity and anti-tumor activity of Ara-C in in vitro studies.
Application
- Oncotherapy resistance explained by Darwinian and Lamarckian models.: This research explores the mechanisms of oncotherapy resistance, combining Darwinian and Lamarckian models to provide a comprehensive understanding. The study highlights the role of Tetrahydrouridine in modulating therapy resistance pathways in cancer treatment (Saunthararajah et al., 2024).
- Neuroendocrine lineage commitment of small cell lung cancers can be leveraged into p53-independent non-cytotoxic therapy.: This study investigates the potential of using Tetrahydrouridine in non-cytotoxic therapies for small cell lung cancers, focusing on neuroendocrine lineage commitment and its implications for treatment efficacy (Biswas et al., 2023).
- In Vitro Interaction of Tetrahydrouridine with Key Human Nucleoside Transporters.: This study explores how Tetrahydrouridine interacts with human nucleoside transporters, shedding light on its mechanisms of action and potential as a therapeutic agent in biochemistry and pharmacology (Säll et al., 2023).
- Mycoplasma infection of cancer cells enhances anti-tumor effect of oxidized methylcytidines.: This research investigates how mycoplasma infection enhances the anti-tumor effects of oxidized methylcytidines, with Tetrahydrouridine playing a crucial role in the observed therapeutic outcomes (Pang et al., 2023).

Hi, may I ask if the THU (Cat number: 18771-50-1) is stable if stored at -4 oC and 10 oC? There is temperature excursion of the freezer in lab, and we would like to check what is the highest tolerable storage Temp which this reagent stored
1 answer-
The recommended storage temperature for this material is −20°C. The product is shipped on ice to maintain the quality of the compound. In general, products of this nature are considered stable within the range of −10 to 25°C. The end user would have to evaluate the integrity of the product for excursions beyond this range.

Does this product have an expiry date?
1 answer-
This product does not contain an expiration date. It contains a recommended retest date of 10 years after the quality release date. A recommended retest date is the period of time during which the product is expected to remain within established stability specifications, provided that it has been stored under defined conditions. After the Retest Date, product samples should be examined to ensure that the product is still in compliance with the established specifications.
