Abstract
Plasma concentrations of ten individual proteins were measured by electroimmunoassay in young male Buffalo rats following injection of turpentine oil or implantation of Morris hepatoma 7777. The highest relative responses to inflammation and tumour growth were found for alpha 2-macroglobulin, alpha 1-acute-phase globulin and alpha 1-acid glycoprotein. As shown by crossed immuno-affinoelectrophoresis the concanavalin A-reactive fractions of the latter two glycoproteins were predominantly increased in plasma from injured and tumour-bearing rats.
