SHIKARI® S-ATA

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

Adalimumab (Humira®) was associated to the development of anti-Adalimumab antibodies, even some were reported to be neutralizing, in various percentages of patients during therapy with the drug Humira®. This might lead to severe complications. The Matriks Biotek Shikari® Antibody to Adalimumab ELISA Kit can be efficiently used for monitoring anti-Adalimumab 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-Adalimumab antibodies.

Total and Free Antibody to Adalimumab (Humira®) ELISA

Drug Tolerant Assay

Enzyme immunoassay for the semi-quantitative determination (screening) of total and free antibodies to adalimumab in serum and plasma.

Free and Total Anti drug Antibody monitoring gained high importance along with measuring free drug from the patient samples. In order to make these measurements simple yet more informative. We have produced SHIKARI® S-ATA DUO to measure Free and Total anti drug antibodies to Adalimumab simultaniously on the same plate. The kit is semi-quantitative and enables follow up of the patients to adjust the dose of the drug and/or frequency of administration


If quantitative and confirmation is needed please refer to SHIKARI® ADA-QNS-HUM.
