Fitc photobleaching
WebApr 6, 2024 · Photobleaching is often used on purpose to quench autofluorescence when using fluorophores that overlap with tissue autofluorescence. Tissues contain endogenous fluorophores, which give the tissue autofluorescence. These endogenous fluorophores fluoresce at around 488 nm and 520 nm, which are the same wavelengths as GFP … WebMar 10, 2016 · The FITC labeling reaction operates on deprotonated amino groups. At pH 3, the amino groups will be almost entirely protonated, so the reaction will not go well. Adjust the pH to a basic pH of at ...
