Drug Names

Generic Name: Human Helicobacter pylori cytotoxin-associated gene A protein IgG, HP-CagA-IgG ELISA Kit

Purpose

Our Human Helicobacter pylori cytotoxin-associated gene A protein IgG,HP-CagA-IgG ELISA Kit is to assay HP-CagA-IgG levels in Human serum, plasma, culture media or any biological fluid.

Principle

This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antigen specific to HP-CagA-IgG Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antigen. Then a Horseradish Peroxidase (HRP)-conjugated antigen specific for HP-CagA-IgG is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain HP-CagA-IgG and HRP conjugated HP-CagA antigen 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 HP-CagA-IgG You can calculate the concentration of HP-CagA-IgG in the samples by comparing the OD of the samples to the standard curve.
