StabilCoat® and 5X StabilCoat® Immunoassay Stabilizers

SurModics StabilCoat® Immunoassay Stabilizer (also available in a 5X concentrated solution) has the exceptional and rare ability to not only preserve the conformation and activity of dried proteins in immunoassays, but to also function as an excellent blocking buffer.

  • StabilCoat Immunoassay Stabilizer is considered the gold standard for stabilizing proteins in the dried state.
  • StabilCoat solution is an excellent blocking agent that can be dried down or used as a blocker for same-day assays.
  • Simply substitute StabilCoat Stabilizer for your usual blocking solution for easy incorporation into most assay protocols.
  • Use it to stabilize antibodies, antigens, or enzymes on an assortment of immunoassay components, such as polystyrene plates, tubes, glass, membranes, and filter paper.

Stability Data

Stability tests were performed with StabilCoat stabilizer using either rabbit monoclonal or polyclonal IgG antibodies (see graph below). Coated microtiter plates were stabilized with either StabilCoat stabilizer or 1% BSA. The antibody-coated plates were dried and placed at room temperature. Percent retained activity was determined by comparing the activity of the aged antibody-coated microtiter plates to that of freshly coated plates. After 30 months in StabilCoat stabilizer at room temperature, the monoclonal antibody retained 70% activity and the polyclonal antibody retained 95% activity.
