Pig CHGA(Chromogranin A) ELISA Kit

Pig CHGA(Chromogranin A) ELISA Kit is a research-use ELISA kit from ELK Biotechnology for measuring CHGA in Serum, Plasma, Tissue homogenates, Other biological fluids samples from Pig. Use the listed assay range, sample guidance and protocol documents to assess suitability for the intended study.

Test principle

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Pig CHGA. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Pig CHGA. 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 Pig CHGA, 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 Pig CHGA in the samples is then determined by comparing the OD of the samples to the standard curve.
