DEVICES AND WASHES FOR BIOMARKER STABILIZATION
Herein are disclosed compositions, washes, rinses, devices, systems and methods for biomarker stabilization, in part in bodily fluids, as well as methods and formulations for improving the sampling and testing of fluids for biomarkers. Included in the disclosure are exemplary embodiments of rinses or washes containing a stabilizing agent to prevent the destruction of a diagnostic agent or biomarker and exemplary systems for the detection of diagnostic biomarkers in a bodily fluid
1 . A rinse useful to stabilize a diagnostic marker, the rinse comprising:
a stabilizing agent useful to completely or substantially prevent degradation or inactivation of a detection agent or a diagnostic marker;
at least preservative; and
a liquid;
wherein the stabilizing agent is selected from the group consisting of aluminum sulfate hydrate, benzoic acid, aluminum potassium sulfate dodecahydrate, and a combination thereof.
2 . The rinse of claim 1 , wherein the stabilizing agent comprises aluminum sulfate hydrate, benzoic acid, and aluminum potassium sulfate dodecahydrate.
3 . The rinse of claim 2 , wherein the preservative is sodium azide.
4 . The rinse of claim 1 , wherein the stabilization agent is useful to completely or substantially prevent degradation or inactivation of a detection agent or a diagnostic marker by a peroxidase.
5 . A system for the detection of a diagnostic marker in a body fluid, the system comprising:
a diagnostic device comprising a plurality of test wells, wherein each test well is capable of containing at least one detection agent;
a detection device capable of interacting with the diagnostic device, wherein the detection device is capable of detecting an interaction between the at least one detection agent and a diagnostic marker in at least one of the plurality of test wells; and
a stabilization agent contained within at least one of the plurality of test wells, the stabilization agent capable of completely or substantially preventing the degradation or inactivation of the detection agent or the diagnostic marker.
6 . The rinse of claim 4 , wherein the stabilizing agent comprises aluminum sulfate hydrate, benzoic acid, and aluminum potassium sulfate dodecahydrate.
7 . The rinse of claim 4 , wherein the stabilizing agent further comprises sodium azide.
8 . The rinse of claim 4 , wherein the stabilization agent is useful to completely or substantially prevent degradation or inactivation of a detection agent or a diagnostic marker by a peroxidase.
