| 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. |
