Descrição geral
Poly (2′-deoxyinosinic-2′-deoxycytidylic acid) sodium salt is an alternating copolymer that acts as a substrate for DNA methyltransferases.
Aplicação
Poly(2′-deoxyinosinic-2′-deoxycytidylic acid) sodium salt has been used in electrophoretic mobility shift assay (EMSA) of the transcription factor AP-2 Alpha (TFAP2A) and in southwestern blotting of human embryonic kidney cells (HEK293) nuclear extract.
Suitable for
- non-specific blocking agent in EMSA
- evaluation of DNA methyltransferases
- DNA-small molecule or drug interaction studies
Ações bioquímicas/fisiológicas
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 as a non-specific competitor in electrophoretic mobility shift assay (EMSA).
