Human Periplakin (PPL) ELISA Kit
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to PPL. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to PPL. 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 PPL, 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 PPL 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.
Target Information
Component of the cornified envelope of keratinocytes. May link the cornified envelope to desmosomes and intermediate filaments. May act as a localization signal in PKB/AKT-mediated signaling.

Performance Characteristics
REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level PPL were tested 20 times on one plate, respectively. |
SENSITIVITY | The minimum detectable dose was 0.114ng/mL. |
ASSAY RANGE | 0.312-20ng/mL |
SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of PPL. No significant cross-reactivity or interference between PPL and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between PPL and all analogs, therefore, cross reactivity may still exist. |
