Abstract
Summary
Basic, high-molecular weight synthetic lysine polypeptides have been found to agglutinate chicken red cells at concentrations as low as 0.1 pg per ml. The hemagglutination titer of the polypeptidea appears to be related to the number and type of amino acid residues per molecule. The polypeptides are enzymatically hydrolyzed by normal allantoic fluid of chicken embryos.
