title: Lack of correlation between structural features and function of synthetic agents tested for leukocyte chemotaxis.
abstract: A number of proteins, poly-L-amino acids, oligopeptides and lipids were tested for neutrophil, eosinophil and macrophage chemotactic activity. One myoglobin preparation was active. Based on the negative findings for all other substances, primary structure, secondary structure, degree of hydrophobicity, size and charge of a molecule, could be ruled out as structural features recognized by chemotactically responding phagocytes.
