Liu's stain is composed of two dyes, Liu A and Liu B. Liu A is the anionic dye, contains eosin Y to stain cytoplasm as well as hemoglobin into red. Liu B, on the other hand, is the cationic dye, contains azur I and methylene azure, to stain nucleus and basophilic granules into blue. To apply the stain on a fixed smear, first add Liu A for some ...

Cell cycle analysis by DNA content measurement is a method that most frequently employs flow cytometry to distinguish cells in different phases of the cell cycle.Before analysis, the cells are usually permeabilised and treated with a fluorescent dye that stains DNA quantitatively, such as propidium iodide (PI) or 4,6-diamidino-2-phenylindole (DAPI).
Flow-FISH was first published in 1998 by Rufer et al. [11] as a modification of another technique for analyzing telomere length, Q-FISH, that employs peptide nucleic acid probes [12] of a 3'-CCCTAACCCTAACCCTAA-5' sequence labeled with a fluorescin fluorophore to stain telomeric repeats on prepared metaphase spreads of cells that have been treated with colcemid, hypotonic shock, and fixation to ...

Immunohistochemistry or IHC staining of tissue sections (or immunocytochemistry, which is the staining of cells), is perhaps the most commonly applied immunostaining technique. [2] While the first cases of IHC staining used fluorescent dyes (see immunofluorescence ), other non-fluorescent methods using enzymes such as peroxidase (see ...
Staining and fluorescent tagging can serve similar purposes. Biological staining is also used to mark cells in flow cytometry, and to flag proteins or nucleic acids in gel electrophoresis. Light microscopes are used for viewing stained samples at high magnification, typically using bright-field or epi-fluorescence illumination.
Think of this creamy skillet casserole as a one-pan taco. The corn tortillas crisp up under the broiler, adding crunch to go with the creamy filling.
