Antibodies to Dermatophagoides pteronyssinus allergen Dpt 12 contaminating rabbit antisera to human and mouse anti-immunoglobulins.
Antibodies to the allergen Dpt 12 from Dermatophagoides pteronyssinus have been demonstrated in commercially obtained rabbit anti-human IgE, IgG and IgA antisera and in a commercially obtained rabbit anti-mouse IgG1 antiserum using either double or triple antibody radioimmunoassays. Where measurable, the titre of anti-Dpt 12 antibodies varied both between different anti-isotypes and between batches of the same anti-isotype as judged by the dilution of antiserum required to bind 50% of the radiolabelled Dpt 12. The titres ranged from 1/23-1/360. In contrast, a specific rabbit anti-Dpt antiserum gave a titre of 1/4500.
