Thymidine is a pyrimidine deoxynucleoside which pairs with deoxyadenosine in double-stranded DNA. Thymidine is a nucleoside composed of a pentose sugar, deoxyribose, and a pyrimidine base thymine. Phosphorylation of thymidine with one, two or three phosphoric acid groups, can form dTMP (deoxythymidine monophosphate), dTDP, or dTTP. Thymidine has been used in cell synchronization in G1/early S phase, to incubate cells in cell-cycle analysis, and as a supplement in HL5-modified medium for cell culture.

hi dear. in my thesis i must to used thymidine santa cruz sc-296542a. but i can not find recommended working concenteration for cell culture. how can find it?

Asked by: polaris722
Thank you for the question. The working concentration of Thymidine (CAS 50-89-5) will depend on various experimental parameters. You might want to consult the background literature available for this reagent. We currently list 3 product references: PMIDs 26408354, 26854824 and 28572030. I hope you will find helpful information for your planned experiments.
