SpecificityAntibodies were raised in goat to human IgA. There is low background fluorescence in normal tissue in contrast to cases of autoimmune desease where IgA is depostited. No cross reactivity with albumine fractions of human serum. No cross reactivity with albumine fractions of animal species.

PurityImmunogen affinity purified
Purification notesFrom the crude polyclonal the crossreactive antibodies were extracted by incubation with Sepharose-bound human IgG and IgM.
Specific antibodies were absorpted by incubation with Sepharose-bound human IgA.
Specific antibodies were eluted by acidic buffer at pH 2.5 followed by neutralisation and dialysis.
After repeated binding with immobilized human IgA a minimum of 65% protein bound.
