Purpose

Our Rat dipeptidyl peptidase IV (DPP IV) ELISA Kit is to assay DPP IV levels in Rat serum, plasma, culture media or any biological fluid

Principle

This ELISA kit uses Sandwich-ELISA as the method. The Micro Elisa strip plate provided in this kit has been pre-coated with an antibody specific to BK. Standards or samples are
added to the appropriate Microglia strip plate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for DPP IV is added to
each Micro Elisa strip plate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain DPP IV and HRP
conjugated DPP IV antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a
wavelength of 450 nm. The OD value is proportional to the concentration of DPP IV. You can calculate the concentration of DPP IV in the samples by comparing the OD of the samples to
the standard curve.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Rat DPP IV were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Rat DPP IV were tested on 3 different plates, 8 replicates in each plate.
