Abstract
The present invention relates to a method for long-term stabilizing a pulmonary surfactant protein, to a stabilized aqueous solution containing a pulmonary surfactant protein, and to a kit for assaying a pulmonary surfactant protein which kit contains, as a component reagent, a stabilized aqueous solution containing a pulmonary surfactant protein. The invention provides a method for stabilizing a pulmonary surfactant protein, the method including causing the pulmonary surfactant protein to be present with a calcium ion and an oxidizing/reducing substance. The invention also provides an aqueous solution containing a pulmonary surfactant protein which has been stabilized by use of a calcium ion and an oxidizing/reducing substance in combination. The invention also provides a kit for assaying a pulmonary surfactant protein present in a sample through an immunological technique employing antigen-antibody reaction, the kit containing, as a standard solution of pulmonary surfactant protein, an aqueous solution containing a pulmonary surfactant protein which has been stabilized by use of a calcium ion and an oxidizing/reducing substance in combination.
