Q: I am using your Bombesin-SAP (Cat. #IT-40) to kill GRP-receptor in mouse brain. I have a plan to inject it by iontophoresis. Do you know which charge dose Bombesin-SAP and Blank-SAP (Cat. #IT-21) have; plus charge or negative charge?
A: Both of these products will have a negative charge, though you may have to look into the literature for any needed guidance on dosing with that type of delivery.
