hey how exactly does dead mans blood work, i mean does the doss of DMB count from blood taken from a corpse that has been dead a while only; or if you take the blood, store it and in the mean while the donor dies is it harmful to vamps; or stored blood in general?

and what if they're sucking someone dry and half way though the donor carks it, do they have to abandon their meal or do the actual cells have to die or something?

this has been bugging me for a while, so any theories?
