EDTA or citrate are common anticoagulates. I'm not sure what the correct concentrations are, but I'm sure that data can be found in medical journals (a lot of studies use anticoagulents)

The vials that we use contain 1.8 mg EDTA per ml blood. Note that in commercial tubes EDTA is sprayed to the walls, which facilitates easy mixing. If you just pipette it in, you have to be quick and ensure thorough mixing.
