Human anti tocilizumab 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 tocilizumab (clone AbD21364_hIgG1) at a concentration of 2 μg/ml in HISPEC 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® | |
Human anti tocilizumab specificity titration ELISA A microtiter plate was coated over night with human IgG1/kappa, human IgG1/lambda or tocilizumab at a concentration of 5 μg/ml. After washing and blocking with PBST+5% BSA, detection was performed using HRP-conjugated Human anti tocilizumab (clone AbD21364_hIgG1) titrated to the given concentrations in PBST, followed by QuantaBlu™ fluorogenic peroxidase substrate. Data presented is the mean of three measurements | |
Tocilizumab bridging ELISA for Pharmacokinetic (PK) assay development A microtiter plate was coated over night with Human anti tocilizumab (clone AbD21362, HCA252) at a concentration of 1 μg/ml. After washing and blocking with PBST+5% BSA, 10% human serum was added spiked with increasing concentrations of tocilizumab. Detection was performed using HRP-conjugated Human anti tocilizumab (clone AbD21364_hIgG1) at a concentration of 2 μg/ml in HISPEC assay diluent (BUF049A) and QuantaBlu™ fluorogenic peroxidase substrate. Data presented is the mean of three measurements. HRP-conjugation of the antibody used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit® | |
Human anti tocilizumab bridging ELISA for Anti-Drug Antibody (ADA) assay development A microtitre plate was coated over night with tocilizumab at a concentration of 1 μg/ml. After washing and blocking with PBST+5% BSA, 10% human serum was added spiked with increasing concentrations of different Human anti tocilizumab clones, AbD21338_hIgG1 (HCA253), AbD21364_hIgG1 (HCA254), AbD21346_hIgG1 (HCA255) and AbD21345_hIgG1 (HCA256). Detection was performed using HRP-conjugated tocilizumab. Data presented is the mean of two measurements. HRP-conjugation of tocilizumab used in this assay was performed using a LYNX Rapid HRP Antibody Conjugation Kit® | |
Human anti tocilizumab inhibits the binding of tocilizumab to human interleukin 6 receptor (IL-6R) A microtiter plate was coated over night with human interleukin 6 receptor at a concentration of 1 μg/ml. After washing and blocking with PBST+5% BSA, a pre-incubated mixture of tocilizumab (0.3 μg/ml) plus increasing concentrations of the monovalent Fab fragment of the inhibitory Human anti tocilizumab clone AbD21364_hIgG (HCA254) or the non-inhibitory clone AbD22155_hIgG1 (HCA257) was added. Free tocilizumab, still capable of binding to the human interleukin 6 receptor-coated plate, was detected using a Mouse anti Human IgG (Fc) CH2 Domain:HRP (MCA647P) and QuantaBlu™ fluorgenic peroxidase substrate. Data is presented as the mean of three measurements |
