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 … 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. hp envy 34 all-in-one philippines

WebDirect detection is suitable for detecting highly expressed antigens. For direct detection, the primary antibody can be conjugated to an enzyme, such as horse radish peroxidase (HRP) or alkaline phosphatase (AP), or a fluorochrome. The benefit of direct detection is that an additional incubation step with a secondary reagent is not necessary. 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...
