Poly(deoxyadenylic-thymidylic) acid sodium（Cat No.:I042930）, often abbreviated as poly(dA-dT), is a synthetic polynucleotide composed of alternating deoxyadenine (dA) and deoxythymidine (dT) bases. It is commonly used in molecular biology and biochemistry as a model for studying nucleic acid structure, replication, and transcription processes. The sodium salt form enhances its solubility, making it suitable for in vitro applications such as primer extension assays, nucleic acid hybridization studies, and the synthesis of RNA. Poly(dA-dT) is also used as a reagent in immunological research, particularly in the activation of certain immune cells like plasmacytoid dendritic cells.
