WebChromogenic detection is useful because it can be easily viewed using a light microscope with no special equipment. Samples also last for many years in storage, and the color doesn't readily... Webin the areas of chemiluminescence and fluorescence have allowed for an easier transition. In non-radioactive assays, signal is generated through an enzymatic reaction with a chemiluminescent or chromogenic substrate; alternatively, detection can occur through the appropriate excitation and emission of a fluorophore-labeled probe.

Non-Radioactive Nucleic Acid Labeling and Detection

WebImmunofluorescence (IF) uses antibodies and fluorescent detection to study the localization, relative expression, and activation states of target proteins in fixed cells or tissues. IF is widely used in diverse fields of study. IF can be used to answer questions such as: What cells or tissues express my target protein(s)? WebFluorescence immunoassays use enzyme substrates that fluoresce when excited by certain light wavelengths. They are usually as sensitive as colorimetric assays but are not limited by higher analyte concentrations. In other words, they can glow more strongly without overwhelming signal detection, thus giving an accurate reading. WebFluorescence Detection Principle: The protein of interest on Western blots can also be detected using primary or secondary antibodies conjugated with fluorescent dyes. The dyes fluoresce at a particular wavelength and can be detected by imaging the blot. Figure 4. Fluorescence detection of proteins on membrane canonic perspective
