Infliximab (Remicade) Pharmacokinetic ELISA Kit
适用物种:Human,mouse,rat

样本类型:Serum,Plasma

检测范围:25ng/ml - 0.78ng/ml

最低检出限:0.78ng/ml

测定时间:2.5 hours

检测格式:Direct sandwich ELISA

检测原理:
The Infliximab ELISA kit is designed to measure free Infliximab with high specificity and sensitivity . This assay employs the sandwich enzyme immunoassay technique. A precoated anti-Infliximab 96 well plate is provided. Calibrator, quality control samples and test samples are pipetted into the appropriate wells. Infliximab present in biological matrices is bound by the immobilized capture antibody. After washing away any unbound substances, enzyme linked detection antibody is added to the wells. 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 Infliximab present in test samples and the concentration is calculated from the standard series.

背景描述:
Infliximab (Remicade®) is a chimeric monoclonal antibody against tumour necrosis factor alpha (TNF- α). Infliximab neutralizes the biological activity of TNF- α by binding with high affinity to the soluble (free floating in the blood) and transmembrane (located on the outer membranes of T cells and similar immune cells) forms of TNF-α, and inhibits or prevents the effective binding of TNF-α with its receptors.

检测程序:
This assay employs the sandwich enzyme immunoassay technique. Anti- Infliximab is coated onto a 96 well microplate. Calibrator, quality control samples (if desired) and test samples are pipetted into the appropriate wells. Infliximab present in biological matrices is bound by the immobilized anti- Infliximab antibody. After washing away any unbound substances, enzyme linked anti- Infliximab antibody is added to the wells. This antibody is developed and purified specifically against truncated Remicade® (domain residing in Fc portion of the Remicade® 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 Infliximab present in test samples. The color development is stopped and the intensity of the color is measured.

样本收集:
This kit is compatible with EDTA-plasma, heparinplasma and serum samples. Samples can be stored at or below -20°C for up to 1 year.

样品制备:
Dilute calibrators and test samples 1/100 with assay buffer (for example add 5µL of prepared calibrator or sample to 495µL of assay buffer). Mix well. *Note that test samples may require further dilution when peak values are predicted to exceed 2.5ug/ml. Do not store diluted samples.

试剂制备:
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 2,500 ng/mL to 78 ng/ mL.

结果计算:
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.
