Interactions of Alkyl Sulphates with Bovine-serum Albumin Studied Using e_aq⁻ as a Probe

Summary

The reactions of hydrated electrons produced during pulse radiolysis have been used to investigate the binding of a range of alkyl sulphates to bovine-serum albumin. Binding to ten high-affinity sites is detectable for all compounds (methyl, hexyl, octyl, decyl, and dodecyl sulphates) studied. Sodium dodecyl sulphate, in contrast to the other analogues, causes large increases in the reactivity of BSA as a result of further binding. Possible mechanisms for this increase are discussed.
