General description

Thymidine is also referred to as pyrimidine deoxynucleoside. Deoxythymidine is a nucleoside present in DNA. In a DNA double stranded structure, thymidine pairs with deoxyadeninosine.

Application

Thymidine can be used in HT and HAT cocktails for hybridoma fusion, selection and cloning. It has been used:
  • as a nucleotide source in minimal essential medium to evaluate the outgrowth of the iSCNT-derived blastocysts
  • as a supplement in Dulbecco′s Modified Eagle Medium (DMEM) selection medium used for the production of anti-neurogranin (NRGN) antibodies
  • to prepare THMG (thymidine, hypoxanthine, glycine, methotrexate) and THG stock solution for cleansing mouse lymphoma cells

Packaging

1, 5, 10, 25 g in poly bottle

Biochem/physiol Actions

Thymidine is useful in cell synchronization during S-phase. In the salvage pathway of pyrimidines, pyrimidine phosphorylase reversibly converts thymine to thymidine.
