Mononuclear cells contain human transfer factor as assayed locally on the skin of dogs.
We prepared transfer factor from mononuclear (M) cells and polymorphonuclear (PMN) cells by sieving cell lysates through a P-2 Biogel column. By assaying column fractions by their ability to induce a local delayed-type reaction to antigen in canine skin, we determined that mononuclear cells most consistently contained skin activity. The elution patterns from P-2 Biogel of PMN or M-enriched preparations were less complex and much different from that seen with whole leukocytes.
