ELISA Kits for Therapeutic Biosimilars


Human IgG based monoclonal antibodies (mAbs) are the fastest-growing category of therapeutics for cancer therapy. Several monoclonal antibodies have received FDA approval for the treatment of a variety of solid tumors and hematological malignancies. Several mechanisms of tumor cell killing by antibodies (mAbs) can be summarized as: direct action through receptor blockade or induction of apoptosis; immune-mediated cell killing by complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC) or regulation of T cell function. United States Biological is pleased to offer one of the largest selections of ELISA Kits for research-grade antibodies. These ELISA Kits can be used to study dose-pendent pharmacokinetics as well as to identify biomarkers for (non-)response and risk factors for adverse drug reactions.

Key Features

  • Rapid and Simple: No expensive equipment or special handling/disposal required
  • Accurate: Reproducible results with low intra & inter assay variability
  • Highly Sensitive and Specific

Sample Standard Curve
*(shown for reference only; user must generate a new standard curve with each assay)

Elisa Kit Image

Rituximab. This standard curve was generated with the supplied calibrator using the recommended conditions and diluted 1 in 50 to give a final concentration range of 100-5ng/ml. Each sample was run with 6 replicates. Intra-assay coefficient of variance is <10%.

Elisa Kit Image

Trastuzumab. This standard curve was generated with the supplied calibrator using the recommended conditions and diluted 1 in 50 to give a final concentration range of 40ng/ml to 1.25ng/ml. Each sample was run with 6 replicates. Intra-assay coefficient of variance is <10%.

Elisa Kit Image

Bevacizumab. The standard curve below was generated with the supplied calibrator using the recommended conditions and diluted 1 in 50 to give a final concentration range of 50-1.56ng/ml. Each sample was run with 6 replicates. Intra-assay coefficient of variance is <10%.
