The fifth component of guinea pig complement, with a sedimentation coefficient 7.8 S, is
cleaved by sensitized sheep erythrocytes treated with the first four components of
complement into two fragments with sedimentation coefficients of 7.4 S and 1.5 S. The
smaller fragment, with a molecular weight of about 15,000, possesses chemotactic activity
for rabbit polymorphonuclear leukocytes, as well as anaphylatoxic activity for guinea pig
ileum.
