WebMar 5, 2024 · Agglutination assays are usually quick and easy to perform on a glass slide or microtiter plate (Figure 20.3. 1 ). Microtiter plates have an array of wells to hold small volumes of reagents and to observe reactions (e.g., agglutination) either visually or using a specially designed spectrophotometer. WebThe BCA assay primarily relies on two reactions. First, the peptide bonds in protein reduce Cu 2+ ions from the copper (II) sulfate to Cu 1+ (a temperature dependent reaction). The amount of Cu 2+ reduced is proportional to the amount of protein present in the solution.
