(A) pH dependence of optical density values of SMA solutions in standard BR buffer, which represent the solubility of the polymers. (B) pH-dependent optical density of solutions of the SMA 2:1 variant in BR buffer at varying ionic strength. All measurements were performed at a polymer concentration of 0.1% w/v. The optical density was measured at λ = 350 nm. Solid lines were added to guide the eye. To see this figure in color, go online.
