Effect of Specific Anti-Sera on C14 Amino Acid Incorporation into Cellular Protein of Mouse Ascites Tumor Cells.

Abstract
Summary Mouse ascites tumor cells exposed to specific anti-sera in the presence of complement failed to concentrate and incorporate labeled amino acid into gross cellular protein. Inhibition of amino acid uptake by specific anti-sera closely parallels cell rupture by anti-sera (in the presence of complement) and this appears to be a rapid and sensitive biochemical assay for antibody produced against mouse ascites tumor cells by the rat.
