How is tetrofosmin labeled?
1. Add up to 240 mCi of Na99mTcO4 in 4-8 mL in kit.
2. Remove 2ml of N2 gas from vial to admit air.
3. Incubate 15min, use w/n 12 hrs.
*Hydrogen radical H+ and hydrated electron e- are reducing species. Letting air into the vial allowes O2 to scavenge the reducing species*
*Tetrofosmin is mixed with gluconate to keep it soluble*
