Human anti natalizumab specificity ELISA

A microtiter plate was coated over night with various antigens at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using HRP conjugated Human anti natalizumab (clone AbD21384_hIgG1) at a concentration of 2 μg/ml, in HISPEC assay diluent (BUF049A) and QuantaBlu fluorogenic peroxidase substrate. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit.
