2-Thiothymidine-5'-Triphosphate (sodium salt/ammonium salt); 100 mM : 1 mL

2-Thiothymidine-5′-Triphosphate (2sTTP) is a modified nucleotide analog of thymidine triphosphate in which the oxygen atom at the 2-position is replaced by sulfur. This modification enhances photoreactivity, UV crosslinking efficiency, and stability in nucleic acid synthesis and biochemical assays.

Supplied as a 100 mM aqueous solution (1 mL) in sodium/ammonium salt form, 2-Thiothymidine-5′-Triphosphate is ideal for use in PCR, DNA polymerase assays, photoaffinity labeling, and studies of DNA-protein interactions. Its incorporation into DNA strands enables site-specific modification for molecular biology and photochemical research applications.
