WebAnother approach to reducing autofluorescence is to treat the tissue sample with dyes that quench fluorescence. These dyes include: Pontamine sky blue Sudan black Trypan blue Paraffin-embedded samples are often more autofluorescent, even though the sample has been thoroughly de-waxed. Webprimary antibody. Since antibody’s Fc domain is constant within the same animal class, only one type of secondary antibody is required to bind to many types of primary antibodies. This reduces the cost by labeling only one type of secondary antibody, rather than labeling various types of primary antibodies. Figure 3. Structure of IgG Protein.
