Harvesting IRAP is relatively straightforward. Blood is collected in a syringe with unique glass beads and left to incubate for 24 hours, leaving the white blood cells to produce massive amounts of anti-inflammatory Interleukin-1 Receptor Antagonist Protein (IRAP). After which, the blood is spun down in a centrifuge where it separates red blood cells, plasma, and platelets. (Here, veterinary assistant, Elle, is removing a blood specimen from the centrifuge to harvest the IRAP serum.) The IRAP protein is in the clear yellow serum that rises to the top of the tube, making it easy to decant (separate) off. A single blood sample can produce 3-6 doses of IRAP. After an initial treatment, any remaining samples are frozen for subsequent treatments. (Learn more: IRAP Therapy – Treating Degenerative Joint Disease.)
