Description

Universal Lateral Flow Strips are ready-to-use, universal test strips (dipstick), which are based on lateral flow technology using gold particles. The strip is designed to develop rapid test systems for several analytes such as proteins, antibodies, or gene amplificons. The user needs to develop an analyte-specific solution, which contains a first detector (e.g. antibody, antigen, specific probe) labeled with FITC and a second one (e.g. antibody, primer) labeled with biotin. 

The strip should be placed directly into the sample solution. No assay buffer is required.

The complexed analyte, labeled with FITC and biotin, binds first to the gold-labeled Biotin-specific antibodies in the sample application area of the dipstick. The gold complexes travel through the membrane, driven by capillary forces. Only the analyte-captured gold particles will bind when they pass the line with the immobilized biotin-ligand molecules and generate a red band (Test band) or blue band (Control band) over time. Unbound gold particles migrate over the control band and will be captured by species-specific antibodies. With prolonged incubation time, the formation of an intensely colored control band appears.
