Fluorescent vs chromogenic detection
WebChoosing between a fluorescent or a chromogenic detection method might be more of a personal preference. Fluorescent detection has the advantage of having the potential to amplify the signal and sometimes being easier to digitally quantify signal. WebFluorescent detection is suitable for multiplex WB experiments where multiple targets can be detected in the same assay using fluorophore conjugates with non-overlapping emission spectra. Fluorescent WB is also ideal for quantitative analysis since detection allows for wide dynamic ranges and signal normalization.
