Human Pepsinogen II CLIA Kit


This Chemiluminescence Immunoassay (CLIA) kit is intended for the quantitative determination of human Pepsinogen II levels in serum using the ECL100 or ECL25 Immunoassay analyzer. Determination of human serum pepsinogen II level would be a useful tool in the aid of diagnosing the functional states of acid gastric mucosa.
For research use only. Not for use in diagnostics procedures.


This CLIA is designed, developed, and produced for the quantitative measurement of human Pepsinogen II level in serum samples. The assay utilizes a two-site “sandwich” technique with two antibodies that bind to different epitopes of Pepsinogen II.

Assay calibrators, controls, or patient samples are added directly to a reaction vessel containing streptavidin coated magnetic particles. Simultaneously, an acridinium ester antibody and a biotin antibody are added. The magnetic particles capture the biotin antibody as well as an immuno complex in the form of “magnetic particles – biotin pepsinogen II antibody – pepsinogen II – acridinium ester pepsinogen II antibody”.
The materials bound to the solid phase are held in a magnetic field while unbound materials are washed away. Then, the trigger solution is added to the reaction vessel and light generated by the reaction is measured with the ECL100 or ECL25 analyzer. The relative light units (RLU) are proportional to the concentration of pepsinogen I in the sample. The amount of analyte in the sample is determined from a stored, multi-point calibration curve and reported in serum pepsinogen I concentration.
