Biotrue keeps at least 13 times more lysozyme, a germ fighting protein, active than the other leading solutions tested1

In the eye, proteins such as lysozyme can be found in two states (native and denatured):

  • Proteins in their native state act as the eye’s inborn germ-fighters, carrying out antimicrobial activity on their own

  • Proteins that have lost their structure (denatured proteins) are lifted and dissolved

Biotrue surrounds lysozyme to keep it active longer

Results of in vitro study evaluating the ability of various multi-purpose solutions (Biotrue, OPTI-FREE PureMoist, OPTI-FREE RepleniSH, OPTI-FREE Express, RevitaLens OcuTec, COMPLETE Easy Rub, and Clear Care) to stabilize lysozyme in the native form under chemical denaturation conditions that typically denature lysozyme. Solutions containing lysozyme were exposed to sodium dodecyl sulfate. Subsequently, activity against Micrococcus luteus was evaluated to assess the ability of solutions to protect lysozyme. Clear Care results from separate in vitro study performed following identical test procedures.
