Hi all

I have Actrapid Penfill human insulin solution with stock concentration of 100 IU/ml. I want to do I.P injection to a mouse at a dose of 0.75 IU/kg. However, if each mouse weighs 20 grams, I can only dose 0.00015 IU per mouse, which is impossible to do with an insulin syringe. Is it OK to dilute the stock insulin solution with saline or anything?
