Application

Poly(deoxyinosinic-deoxycytidylic) acid (Poly(dI-dC) • Poly(dI-dC)) is an alternating copolymer used as a DNA substrate for evaluation of DNA methytransfeases, such as DNA-methyltransferase 1 and as double-stranded DNA model for conformational studies of DNA structure dynamics and drug, small molecule, interactions.
Poly(deoxyinosinic-deoxycytidylic) acid sodium salt has been used in a study that synthesized and characterized bis(2-(pyrimidin-2-γl)ethoxy)alkanes and their pharmacological activity. Poly(deoxyinosinic-deoxycytidylic) acid sodium salt has also been used in a study that investigated the growth of calcium carbonate films on LB/LbL matrices.
Poly(deoxyinosinic-deoxycytidylic) acid sodium salt has been used in the electrophoretic mobility shift assay in p65 protein and neuro-2A protein lysate. It has also been used as a substrate in the protein arginine methyltransferase 1 (PRMT1) and DNA methyltransferase 1 (DNMT1) selectivity assay.

Biochem/physiol Actions

Poly(2′-deoxyinosinic-2′-deoxycytidylic acid), poly(dI-dC) is a synthetic DNA substrate. At high salt, Poly(dI-dC) exists in left handed helical conformation and reverts to right-handed form upon decreasing salt. It is used in electrophoretic mobility shift assay (EMSA).

Other Notes

Double-stranded alternating copolymer
One unit will yield an A260 of 1.0 in 1.0 ml of 20 mM sodium phosphate/100 mM NaCl, pH 7.0 (1 cm light path)

This paper focuses on DNA-binding interactions exhibited by Pt(dma-T)CN(+), where dma-T denotes 4'-dimethylamino-2,2':6',2''-terpyridine, and includes complementary studies of the corresponding pyrr-T complex, where pyrr-T denotes 4'-(N-pyrrolidinyl)-2,2':6',2''-terpyridine. The chromophores are useful for understanding the interesting and rather intricate DNA-binding interactions exhibited
