Why Antibody Lots Differ Significantly

Since antibodies first attained prominence as research reagents in modern biological science labs, researchers have been perplexed as to why one production lot can differ significantly from the next, in terms of performance. Poor antibody performance has caused the loss of countless hours of research, to say nothing of the mental anguish of the researchers themselves. An antigen is a substance that stimulates the production of antibodies.
