2-Thio-UTP is a base-modified ribonucleoside triphosphate commonly used in RNA-based biomedical research Incorporation of 2-Thio-UTP into RNA transcripts reduces innate immune activation compared to unmodified RNA Mechanistically RNAs transcribed with 2-Thio-UTP lack the ability to activate RNA-dependent protein kinase (PKR) markedly diminish 2 -5 -oligoadenylate synthetase (OAS) pathway induction decrease recognition by retinoic acid-inducible gene I (RIG-I) and suppress Toll-like receptor (TLR) mediated signaling Thus 2-Thio-UTP serves as a research tool in studies designing low-immunogenic RNAs for therapeutic applications

Aminoallyl-dUTP (CAS 116840-18-7) is a modified deoxynucleotide designed for indirect covalent labeling of DNA or cDNA in molecular biology research Structurally analogous to natural dTTP it incorporates into DNA via enzymatic reactions including PCR (Taq polymerase) nick translation primer extension (Klenow exo-) terminal labeling (TdT) and reverse transcription (MMLV RT) The introduced primary amine moiety enables subsequent conjugation to NHS-activated labels such as fluorophores for fluorescence microscopy or biotin for affinity-based purification and detection strategies including in situ hybridization
