- Applikationshinweise
-
- Before performing the assay, samples and assay kit should be brought to room temperature (about 30 minutes beforehand) and ensure the homogeneity of the solution.
- All Standards should be run with each series of unknown samples.
- Standards should be subject to the same manipulations and incubation times as the samples being tested.
- All steps of the test should be completed without interruption. 6
- Use new disposable plastic pipette tips for each reagent, standard or specimen in order to avoid cross contamination.

- Protokoll
- This is a sandwich type ELISA. Standards and diluted samples (serum or plasma) are incubated in the microtitre plate coated with recombinant human TNF-a (rh TNF-a). After incubation, the wells are washed. A horseradish peroxidase (HRP)-conjugated anti-human IgG monoclonal antibody is added and binds to the Fc part of Infliximab pre-captured by the rh TNF-a on the surface of the wells. Following incubation, the wells are washed and the bound enzymatic activity is detected by addition of chromogen-substrate. The colour developed is proportional to the amount of Infliximab in the sample or standard. Results of samples can be determined directly by using the standard curve.
- Aufbereitung der Reagenzien
-
Just the wash buffer has to be prepared by diluting the stock solution 1:20. All other reagents are ready to use.
- Probennahme
- Normal serum or plasma collection
- Aufbereitung der Proben
-
dilute the samples 1:20 with assay buffer
