Immunogen affinity purified
From the crude polyclonal the crossreactive antibodies were extracted by incubation with Sepharose-bound human IgM and IgG.
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.
The purified polyclonal was conjugated to horseradish peroxidase according to the periodate method followed by gel-filtration and ion-exchange chromatography to clear unbound conjugate.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
