The Dipeptidyl Peptidase 4, DPP4 ELISA kit is used as an analytical tool for quantitative determination of Human Dipeptidyl Peptidase 4, DPP4 in serum, plasma and other biological samples. The Dipeptidyl Peptidase 4, DPP4 ELISA Assay Kit is for research use only and not to be used for diagnostic procedures.
Size: 12 x 8 wells
Standard Range: 500 – 8000 pg/ml
Sensitivity: 497 pg/ml
Sample Type: Biological Samples
Assay Principle
The method employs sandwich ELISA technique. Human Dipeptidyl-Peptidase 4(DPP4) monoclonal antibody are pre-coated onto microwells. Samples and standards are pipetted into microwells and Human Dipeptidyl Peptidase 4, DPP4 present in the sample are bound by the antibodies. Biotin labeled Dipeptidyl-Peptidase 4(DPP4) antibody is added and followed by Streptavidin-HRP is pipetted and incubated to form a complex. After washing microwells in order to remove any non-specific binding, the substrate solution (TMB) is added to microwells and color develops proportionally to the amount of Human Dipeptidyl Peptidase 4, DPP4 in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
Sample Preparation and Storage
Specimens should be clear and non-hemolyzed. Samples should be run at a number of dilutions to ensure accurate quantitation.
1. Extract as soon as possible after specimen collection as per relevant procedure. The samples should be tested as soon as possible after the extraction. Alternately the extracted samples can be kept in -20°C. Avoid repeated freeze-thaw cycles.
2. Serum- Coagulate at room temperature for 10-20 minutes;
