Description_x000D_ General description_x000D_ 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._x000D_ Application_x000D_ Thymidine has been used:_x000D_ • as a supplement in HL5-modified medium for cell culture_x000D_ • to incubate cells in cell-cycle analysis_x000D_ • in cell synchronization_x000D_ Packaging_x000D_ 1, 5, 10, 25 g in poly bottle
