Description

Background:
Epratuzumab (planned trade name LymphoCide) is a humanized monoclonal antibody. Potential uses may be found in oncology and in treatment of inflammatory autoimmune disorders, such as systemic lupus erythematosus (SLE). Epratuzumab binds to the glycoprotein CD22 of mature and malignant B-cells. Elevated CD22 and other B-cell receptor (BCR) proteins are associated with SLE.

Intended Use:
For Estimation of Epratuzumab (LYMPHOCIDE) in human serum and plasma. Please note the kit has not been optimized to be used for any other animal species. Should you require a specific sera tested, please connect with us at sales@krishgen.com for optimization.

Principle:
The method employs the quantitative sandwich enzyme immunoassay technique. Antibodies to Epratuzumab are pre-coated onto microwells. Samples and standards are pipetted into microwells and human Epratuzumab present in the sample are bound by the capture antibody. Then, a HRP (horseradish peroxidase) conjugated anti-Epratuzumab antibody is pipetted and incubated. After washing microwells in order to remove any non-specific binding, the ready to use substrate solution (TMB) is added to microwells and color develops proportionally to the amount of Epratuzumab in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
