INTENDED USEDiagnostic Kit for Calprotectin(cal) is is a colloidal gold immunochromatographic assay for the semiquantitative determination of cal from human faeces, which has important accessory diagnostic value for inflammatory bowel disease. This test is a screening reagent. All positive sample must be confirmed by other methodologies. This test is intended for healthcare professional use only. Meanwhile, this test is used for IVD, extra instruments are not needed.SUMMARYCal is a heterodimer, which is composed of MRP 8 and MRP 14. It exists in neutrophils cytoplasm and expressed on mononuclear cell membranes. Cal is acute phase proteins, it has a well stable phase about one week in human faeces, it is determined to be a inflammatory bowel disease marker. The kit is a simple, visual semiqualitative test that detects cal in human faeces, it has high detection sensitivity and strong specificity. The test based on high specificit double antibodies sandwich reaction principle and gold immunochromatographic assay analysis technics, it can give a resultwithin 15 minutes.PRINCIPLE OF THE PROCEDUREThe strip has anti cal coating McAb on test region and goat anti-rabbit IgG antibody on control region, which is fastened to membrane chromatography in advance. Lable pad is coated by colloidal gold labeled anti cal McAb and colloidal gold labeled rabbit IgG antibody in advance. When testing positive sample, the cal in sample comined with colloidal gold labeled anti cal McAb, and form immune complex, as it is allowed to migrate along the test strip, the cal conjugatecomplex is captured by anti cal coating McAb on the membrane and form “anti cal coating McAb-cal-colloidal gold labeled anti cal McAb” complex, a colored test band appeared on test region. The color intensity is positively correlated with the cal content. A negative sample does not produce a test band due to the absence of colloidal gold conjugate cal complex. No matter cal is present in sample or not, there is a red stripe appear on reference region and quality control region, which is regarded as quality internal enterprise standards.Company Profile
