Researchers from American Red Cross describe findings in virology

Data detailed in "The use of rabbit polyclonal antibodies to assess neoantigenicity following viral reduction of an alpha-1-proteinase inhibitor preparation" have been presented. "The objective of this study was to determine whether the viral reduction processes of nanofiltration and solvent/detergent treatment used in the manufacture of alpha-1 proteinase inhibitor (API) cause neoantigenic changes. Polyclonal antibodies were raised in rabbits against the treated API and quantitatively absorbed with an affinity column containing API that had not undergone viral reduction treatment," investigators in the United States report.

"Antibodies before and after absorption were...
