Polyadenylic acid potassium (Poly(A)) is a polyribonucleotide. Polyadenylic acid potassium constitutes the 3'-poly(A) tail of eukaryotic mRNAs, governing mRNA maturation, stability, and translation initiation. Polyadenylic acid potassium serves as a target for studying nucleic acid structure-function relationships, with small molecules binding its tail influencing mRNA function and protein production. Polyadenylic acid (potassium) can be used for the research of cancer.

Poly (G) (Polyguanylic acid) is a high-molecular-weight synthetic ribopolynucleotide. In the presence of Na⁺ or K⁺ ions, Poly (G) undergoes time-dependent structural modification, gradually self-assembling from a single strand into large G-quadruplex aggregates. Poly (G) undergoes cooperative secondary structure dissociation under alkaline conditions, but its secondary structure can withstand high temperatures up to 100°C and is resistant to snake venom diesterase at low Na⁺ concentrations. Poly (G) forms stable 1:1 complexes with polycytidylic acid or poly 5-bromocytidylic acid, but does not bind to polyinosinic acid or polyadenylic acid. Poly (G) can be applied to studies on the interactions between drugs and G-rich DNA fragments in electrochemical biosensors.

Poly (U) (Polyuridylic acid) is an RNA chain that exists in a disordered extended state at room temperature and serves as a TLR7 ligand. Poly (U) produces distinguishable blocking effects when transported through α-hemolysin nanopores. Poly (U) forms a triple helix with adenosine or adenosine monophosphate, thereby significantly promoting the nucleotide bond condensation reaction between adenosine monophosphate and adenosine, while exerting minimal effects on other nucleosides. When conjugated with cationic lipids, Poly (U) specifically stimulates plasmacytoid dendritic cells to produce type I interferons.

Poly(C) (Polycytidylic acid) is a pleiotropic immunostimulant that specifically binds to TLR3, RIG-I and MDA5 receptors. Poly (C) recruits adaptor proteins to activate downstream signaling pathways and induce the production of type I interferons and inflammatory cytokines. Poly (C) triggers cancer cell apoptosis via the intrinsic or extrinsic caspase pathway, thereby exerting inhibitory effects on tumor growth and metastasis. Poly (C) acts as a vaccine adjuvant to modify the tumor microenvironment, regulate the expression of endothelial adhesion molecules and induce virus-like immune responses. Poly (C) can be applied to research related to melanoma, various solid tumors, hematological malignancies and autoimmune insulin-dependent diabetes mellitus.
