title: Improved method of purifying some radiolabeled glycopeptide hormones.
abstract: We describe a simplified method for purifying radiolabeled glycopeptide hormones (thyrotropin, lutropin, follitropin, and human choriogonadotropin), which results in preparations of over 95% immunoreactivity. This method is based on competitive elution from columns of the plant lectin, concanavalin A, and is applicable to glycopeptide hormones derived from several species.
