WebConsiderations that must be made when choosing fluorochromes include the brightness of the dyes in question, the instrument configuration, and the staining protocol. Each of these factors will impact the quality of the … WebThat is, set compensation based on staining cells with each antibody fluorochrome individually. Next, fine-tune compensation set up with 2-color stained controls. For this 2-color control step, staining exclusive positive populations and a negative population is the most helpful for adjusting fluorescence signal along the appropriate axes.

Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several π bonds. Fluorophores are sometimes used alone, as a tracer in fluids, as a dye for staining of …
