ALKYL SULFATES & SULFONATES

The following products have shown to have excellent binding and stability characteristics in protein chemistry J.Amer.oil Chem. Soc., Apr., 1962, Vol.XXXIX, No.4, Methods of Analyzing Industrial Aliphatic Liquids, Mangolds, H.K. and Kammereck, R., U. of Minn., The Hormel Institute, Austin, Minn.

An example of their use is where native BSA has a total of ten binding sites to C8-C14 sulfates and C8-C12 sulfonates. The number os sites increases with hydrocarbon tail length, and while the interaction energy is not a function of chain length in the case of sulfates, it becomes chain length dependent in the case of sulfonates. Binding affinities are also strongly dependent on the character of the polar portionof the ligand:sulfate and sulfonate groups participate with different energy contributions.

Also, for the measurement of the binding isotherms and the corresponding interaction energies for alkyl sulfates and sulfonates on proteins, as well as ORD and viscosity data, furnishing important knowledge on the short-range forces and the molecular shape of proteins.

Additional elaboration of this area can be found in "Multiple Equilibria In Proteins", Acac. Press, N.Y. (1969) by J.Steinhart and J.Reynolds. All products are analyzed by elemental analysis and occasionally by GC, reflecting purities of 98-99+%.

Aklyl Sulphate and Sulfonate Kits are available to those desiring a small amount of each product for initial investigations. Larger amounts including kilo amounts can be prepared upon request.

We have recently added Heptyl and Octyl sulfonate as the ammonium salt.
