Thymidine (胸苷或胸腺嘧啶核苷)是脱氧核糖核酸的一种特殊前体,被用作细胞同步剂。Thymidine 是一种 DNA 合成抑制因子,它能在 DNA 复制前在 G1/S 边界阻滞细胞。
Thymidine, a specific precursor of deoxyribonucleic acid, is used as a cell synchronizing agent. Thymidine is a DNA synthesis inhibitor that can arrest cell at G1/S boundary, prior to DNA replication.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
