title: A micro-radioimmunoassay for apamin.
abstract: A radioimmunoassay is described which allows detection of quantities of apamin between 5 and 1200 fmoles (10-2400 pg) in 50 microliter aliquots. The assay requires a few milliliters of apamin antiserum diluted 10,000-20,000 times and 125I apamin at a specific radioactivity of 2000 Ci/mmole. This assay is specific for apamin.
