GoStix Plus assays are life science research tools designed for rapid quantification of diverse analytes using a simple, lateral flow-based method. 10 minutes after applying your sample, a band will appear in the window of the GoStix Plus cassette at an intensity that correlates with the amount of analyte present. The cassette is then scanned using a smartphone camera or equivalent mobile device running the GoStix Plus app, which will then quantify the level of analyte in the sample based on the intensity of the band.
