SHIKARI® Q-ATI


Enzyme immunoassay for the quantitative determination of specific antibodies to infliximab in human serum and plasma with confirmation.

Infliximab (Remicade) was associated to the development of anti-Infliximab antibodies, even some were reported to be neutralizing, in various percentages of patients during therapy with the drug Remicade®. This might lead to severe complications. The Matriks Biotek shikari Antibody to Infliximab ELISA Kit can be efficiently used for monitoring anti-Infliximab antibodies during therapy and offers the clinician a tool for decision on possible preventive measures such as possible addition of immunosuppressive drug to reduce anti-Infliximab antibodies.

USE YOUR DRUG EFFECTIVELY AND SAFELY

Check anti-infliximab antibodies in your patients sera with Q-ATI, escalate the dose or combine with (e.g.) methotrexate when needed.
