Common and effective blood coagulants & decoagulants?

[Z-Dub]

For an experiment I need to be able to vary the level of coagulation in a sample of pig blood. What are some effective agents that I can use to coagulate and decoagulate the blood? It would be helpful if the chemicals are easily obtained and relatively inexpensive.

Some common anticoagulants are heparin, sodium citrate, EDTA, fluoride oxalate.
Of the four, sodium citrate would be the cheapest and easiest to obtain, and safest to use. Many chemists might have some in powder form, which you could make up as a liquid with sterile saline, and add to your blood.
These are anticoagulants. Decoagulants, as in substances which break up clots, may not work well in-vitro, they are used in-vivo, via intravenous drips etc. Most commonly this is heparin or warfarin, but aspirin (salicylate) could also be used.
