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

Application

Thymidine has been used:
  • as a supplement in HL5-modified medium for cell culture
  • to incubate cells in cell-cycle analysis
  • in cell synchronization
