Revvity Thymidine, -, 5mCi (185MBq)

5 mCi quantities of [6-³H]-Thymidine are available for your research. Application of [³H]Thymidine can be found in: carboxy-terminal PTH fragments stimulating incorporation in vascular endothelial cells, quantification of granulocyte-macrophage colony-stimulating factor (GM-CSF) hypersensitivity in juvenile myelomonocytic leukemia (JMML), influence of parasympathetic non-adrenergic, non-cholinergic mechanisms on uptake (rat) in response to mastication, measurement of dendritic cell induced T cell response by intracellular ATP levels and uptake in human immunology, etc.

Special Information: If aqueous solutions of thymidine are stored frozen (-20°C), care should be taken to protect the material from U.V. light during the thawing process to prevent possible dimerization.

When [methyl-³H]thymidine is incorporated into cellular DNA and undergoes radiolytic decomposition, [³H]5-hydroxymethyl-2-deoxyuridine (HMdU) is formed.* The formation of HMdU through transmutation of [methyl-³H]thymidine occurs at the rate of B-decay, which is 0.017% per day. The transmutation product is not volatile.
