In lay persons terms, what are BioFX’s products and how do they work?
BioFX develops, manufactures, and markets high sensitivity substrates. Substrates are generally categorized into two types: colorimetric and chemiluminescent, both of which BioFX produce. These substrates are used to detect and signal reactions within manual and automated diagnostic tests so that a result can be recorded. For example, in one type of diagnostic test, an unknown amount of antigen in a sample is immobilized on a surface. A patient sample containing antibody is added over the surface. This antibody is linked to a detection molecule (i.e., an enzyme) that visibly reacts when activated–for instance, light hitting a fluorescent enzyme. The brightness of the fluorescence would then tell you how much antigen is in your sample. The detection methods for colorimetric substrates and chemiluminescent substrates are a spectrophotometer and luminometer, respectively.
