EFdA-TP tetralithium
Based on 1 publication(s) in Google Scholar
EFdA-TP tetralithium is a potent nucleoside reverse transcriptase (RT) inhibitor. EFdA-TP tetralithium inhibits RT-catalyzed DNA synthesis as an effective immediate or delayed chain terminator (ICT or DCT). EFdA-TP tetralithium inhibits HIV-1 RT with multiple mechanisms.

Biological Activity
EFdA-TP (0.05-10 μM; for 15 min) tetralithium inhibits RT-catalyzed DNA synthesis as an ICT or DCT[1].
EFdA-TP tetralithium can block RT as a translocation-defective RT inhibitor that dramatically slows DNA synthesis, acting as a de facto immediate chain terminator[1].
EFdA-TP tetralithium can function as a delayed chain terminator, allowing incorporation of an additional dNTP before blocking DNA synthesis[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
H2O : ≥ 100 mg/mL (179.56 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
