SensitivityThe minimum detectable dose of PTPRF is typically less than 0.31ng/mL. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two
Intended UseHuman PTPRF ELISA Kit allows for the in vitro quantitative determination of PTPRF , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
StorageFor 5-7days:Store the whole kit at 4℃
For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃.
Product Description specificalPrinciple of the assay: The microtiter plate provided in this kit has been pre-coated with an antibody specific to PTPRF. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to PTPRF. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain PTPRF, 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 PTPRF in the samples is then determined by comparing the O.D. of the samples to the standard curve.
