Stabilizing reagent for membrane immunoassay
A method for immunoassay for a ligand is performed on a porous membrane wherein the signal detected is development of a color on the membrane. The color of the signal and background is substantially stopped and stabilized for reading of the assay at a later time by passing a color stabilizing reagen...

| Zusammenfassung: | A method for immunoassay for a ligand is performed on a porous membrane wherein the signal detected is development of a color on the membrane. The color of the signal and background is substantially stopped and stabilized for reading of the assay at a later time by passing a color stabilizing reagent which includes an acid through the membrane. |
