General description
Poly(dA) is a polymer of polydeoxyadenylic acid and takes up a single stranded structure. It is susceptible to UV irradiation resulting in photoreaction due to the presence of adjacent deoxyadenylic acid units. Poly(dA) along with β-glucan is used for the conjugation and delivery of DNA into cell lines.
Application
Poly(dA) is suitable for use in:
- DNA polymerase assay and as a buffer component for the dilution of protein DNA complex for electrophoretic mobility shift assay (EMSA) studies
- as ssDNA substrate for DNA helicase gene 40 product (G40P) NTP hydrolysis
- in Pyrococcus abyssi DNA polymerase assay
Sequence
Chain Length Mean chain length lot 20-17: 250-500 bases.
Unit Definition
1 A260 unit corresponds to 40 μg ssDNA.

Many yeast promoters contain homopolymeric dA:dT sequences that affect nucleosome formation in vitro and are required for wild-type levels of transcription in vivo. Here, we show that poly(dA:dT) is a novel promoter element whose function depends on its intrinsic structure
