The study describes an in vitro method to assess chemotactic activity of soluble substances on motile cells. The method involves incubating antibody‑antigen mixtures at 37 °C in fresh rabbit serum to elicit chemotaxis of polymorphonuclear leukocytes. Incubation of antibody‑antigen complexes in fresh serum generates a heat‑stable chemotactic substance that directly stimulates polymorphonuclear leukocytes, a substance absent when the serum is pre‑heated to 56 °C for 30 min.
An in vitro technique is described for assessing the chemotactic activity of soluble substances on motile cells. Antibody-antigen mixtures when incubated (37 degrees C) in medium containing fresh (i.e. non-inactivated) normal rabbit serum exert a strong chemotactic effect on rabbit polymorphonuclear leucocytes. Results are described which indicate that, when antibody-antigen complexes are incubated (37 degrees C) in fresh serum, a heat-stable (56 degrees C) substance (or substances) is produced which acts directly as a chemotactic stimulus on the polymorphs. This heat-stable chemotactic substance is not produced when antibody-antigen complexes are incubated in serum which has been heated at 56 degrees C for 30 minutes.
