What are TCK kits?
These are kits for the preparation of a particular 99mTc radiopharmaceutical. Generally a kit contains lyophilized formulation of premixed reagents of ligand, reducing agent, Sn (II) as SnCl2.2H2O, lyoprotectant, stablizer and additives in appropriate concentration and pH. This kit, when reconstituted with sterile sodium pertechnetate, in the manner specified for the product, yields the desired radipharmaceutical in sterile injectable form.
