WebNotice that the FITC tops out at ratio of 6 for this molecule, whereas Alexa488 keeps getting brighter. Thus, the brightness of your reagent is tied to the F/P ratio. If the F/P on the target antigen is lower than for the isotype control, the observed signal for the isotype could be higer for this reason, not due to more binding. WebFITC (Ex-Max 494 nm/Em-Max 520 nm): Fluorescein isothiocyanate - has a very high efficiency of energy transfer from absorbed to emitted light and is one of the most commonly used fluorochromes. However, FITC is highly sensitive to pH changes and photo bleaching. In addition FITC is relatively dim and should be reserved for highly expressed markers …
