The process for producing a colloidal component of a diagnostic agent for indirect lymphoscintigraphy

摘要

A process for preparing a colloidal component of a diagnostic agent for indirect limfostsintrigrafii prepared by mixing ammonium perrhenate, gelatin, sodium thiosulfate and hydrochloric acid, characterized in that the colloidal solution is prepared at a temperature of 70-80 ° C at a molar ratio of ammonium perrhenate and sodium thiosulphate of 1: 35- 45, neutralized with sodium hydroxide, dialyzed against physiological saline and passed through a sterilizing filter.
