Mouse Regenerating Islet Derived Protein 4 (REG4) ELISA Kit
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to REG4. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to REG4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain REG4, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of REG4 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.

Performance Characteristics
REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level REG4 were tested 20 times on one plate, respectively. |
SENSITIVITY | The minimum detectable dose was 20.7pg/mL. |
ASSAY RANGE | 46.8-3000pg/mL |
SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of REG4. No significant cross-reactivity or interference between REG4 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between REG4 and all analogs, therefore, cross reactivity may still exist. |
