Abstract: The present invention provides reagents and methods for limiting adsorptive and/or oxidative protein losses in a sample.

Abstract: Compositions are disclosed containing a solvated viscoelastic polymeric gel diluted into an ionically conductive aqueous solution which can be usefully applied to any surface that is hydrophobic to act, for example, as an antifogging coating with minimal optical distortion and excellent transparency. The compositions can also be used as lubricious agents on medical implants, shunts, and surgical supplies to minimize tissue trauma, to maximize bio-compatibility, and to increase healing by enhancing better irrigation and flow in adjacent tissue.
