Purpose

Our Rat calcitonin gene related peptide, CGRP ELISA Kit is to assay CGRP 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 CGRP. Standards or samples
are added to the appropriate Micro Elisa strip plate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for CGRP 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 CGRP and HRP conjugated CGRP 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 CGRP. You can calculate the concentration of CGRP 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 CGRP were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Rat CGRP were tested on 3 different plates, 8 replicates in each plate.
