Neutralizing Activity in Isolated Serum Antibody Fractions from Visna-Infected Sheep

P D Mehta 1, H Thormar 1
PMCID: PMC423005  PMID: 4372177

Abstract

The neutralization technique was used to detect specific antibodies against visna virus in isolated immunoglobulin (Ig) G1, IgG2, and IgM fractions of visna-infected sheep serum. The neutralizing antibodies were present chiefly in the IgG1 class. Low amount of activity was demonstrated in the IgM class, but no significant activity was seen in the IgG2 class.
