【Intended use】

This product is used for in vitro qualitative / quantitative detection of S100β Protein / D-dimer / Lipoprotein-Associated Phospholipase A2 (Lp-PLA2) in human whole blood, serum or plasma specimens.

【Assay principle】

This kit adopts the principle of colloidal gold chromatographic immunoassay . Antibodies against target proteins are coated with gold particles which are stored in the test strip. During testing, the target protein in the specimen reacts with those antibody-coated particles and forms a complex. The complex then migrates upward on the membrane chromatographically by capillary action. When the complex reaches the detection area (T line), the monoclonal antibody recognizing the target protein in the T-line area captures the complex, which cause the complex precipitating in the T-line area. A colorful line appears in the T-line area, which indicates a positive result. If the speciman does not contain the target protein, no complex is formed. Therefore no colorful line appears in the T-line area, which indicates a negative result. The unbound colloidal gold moves forward along the nitrocellulose membrane to the quality control area (C-line) by capillary action then is captured by the goat anti-mouse IgG antibody coated on the nitrocellulose membrane at C-line area. The colloidal gold precipitates in the C-line area and a colorful line appears there. C-line serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred. The results can be determined qualitatively by visual observation or quantitatively by using a colloidal gold immunochromatographic analyzer.
