Rituximab targets CD20, which is expressed on the surface of B cells, to induce apoptosis in B cells and is used in the treatment of leukemias and lymphomas, some autoimmune disorders, and organ transplant. A quantitative method for Rituximab has been developed and optimized for pharmacokinetic assessment of samples.\u003c\/p\u003e\n\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget Drug:\u003c\/strong\u003e Rituximab (Rituxan)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e ELISA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Quantification of Rituximab in biological matrices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMethod:\u003c\/strong\u003e Direct sandwich ELISA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Method:\u003c\/strong\u003e Peroxidase \/ OD450\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReactivity:\u003c\/strong\u003e Human, mouse, rat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Range:\u003c\/strong\u003e 100ng\/ml - 5ng\/ml\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Minimum:\u003c\/strong\u003e 5ng\/ml\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSample Type:\u003c\/strong\u003e Serum Plasma\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSample Volume:\u003c\/strong\u003e 15ul\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssay Time:\u003c\/strong\u003e 2.5 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e -20C, 1 year\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping:\u003c\/strong\u003e dry ice, less than -20C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Size:\u003c\/strong\u003e 1X96 wells\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecificity:\u003c\/strong\u003e Rituximab\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlate Format:\u003c\/strong\u003e Strip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKit Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponents:\u003c\/strong\u003e Coated microtiter plate, 96 wells\nCalibrator diluent. - 1.8ml\nCalibrator 12ul\n10X wash buffer - 25ml\nAssay buffer - 50ml\n1000X detection reagent - 17ul\nTMB - 12ml\nTMB stop solution - 12ml\nPlate sealers - 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssay Procedure:\u003c\/strong\u003e This assay employs the sandwich enzyme immunoassay technique. Anti- Rituximab is coated onto a 96 well microplate. Calibrator, quality control samples (if desired) and test samples are pipetted into the appropriate wells. Rituximab present in biological matrices is bound by the immobilized anti- Rituximab antibody. After washing away any unbound substances, enzyme linked anti- Rituximab antibody is added to the wells. This antibody is developed and purified specifically against truncated Rituxan® (domain residing in Fc portion of the Rituxan® molecule). The plate is washed to remove any unbound antibody-enzyme reagent and a substrate solution is added to the wells for color development. The color development is proportional to the amount of Rituximab present in test samples. The color development is stopped and the intensity of the color is measured.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReagent Preparation:\u003c\/strong\u003e Prepare the appropriate amount of required reagent on the day of use. Store all reagents as per instructions stated on the label. 1. Wash Buffer (1X) Preparation: Dilute wash buffer concentrate with ultra-pure water 1\/10 before use (for example add 20mL concentrate to 180mL ultra-pure water). Mix well. 2. Detection Reagent (1X) Preparation: Dilute detection reagent with assay buffer 1\/1000 before use (for example add 11μl concentrate to 11ml of assay buffer). Mix well. 3. Preparation of Calibrators: Prepare calibrators with concentrations ranging from 5000 ng\/mL to 250 ng\/ mL. The following is an example calibrator curve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResults Calculation:\u003c\/strong\u003e 1. Construct a standard curve by plotting the absorbance obtained from each standard against concentration. Use a 4 or 5 parameter curve fit. Alternatively a log-log curve fit may be used. 2. The concentration of the unknowns can be read directly from this standard curve using the absorbance value for each sample. 3. Any sample undiluted or diluted still reading greater than the highest standard should be diluted appropriately with assay buffer and retested. If the samples have been diluted, the concentration determined from the standard curve must be multiplied by the dilution factor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSample Collection:\u003c\/strong\u003e This kit is compatible with EDTA-plasma, heparinplasma and serum samples.

Mix well. *Note that test samples may require further dilution when peak values are predicted to exceed 5ug\/ml.
