title: Technical note: is there a season for iodinating relaxin?
abstract: We report a loss of antibody binding in our porcine relaxin radioimmunoassay that has occurred during the coldest periods of the past three winters. We do not know the reason for this seasonal variation but we have eliminated cold deterioration of the iodide used for radioiodination and equipment failures as explanations.
