Propidium Iodide (PI) is a nuclear staining agent that stains DNA. Propidium Iodide is an analogue of ethidine bromide that emits red fluorescence upon embedding in double-stranded DNA. Propidium Iodide cannot pass through living cell membranes, but it can pass through damaged cell membranes to stain the nucleus. Propidium Iodide has a fluorescence wavelength of 493/617 nm and a wavelength of 536/635 nm after Mosaic with DNA. Propidium Iodide is commonly used in the detection of apoptosis (apoptosis) or necrosis (necrosis), and is often used in flow cytometry analysis.

Light green SF yellowish (Acid Green 5) is a water-soluble triarylmethane dye. Light green SF yellowish serves as a histological stain that selectively labels mitochondria, collagen, and cartilage, while being an essential component of Papanicolaou staining. Light green SF yellowish is commonly used as a cytoplasmic counterstain for nuclear stains, and is applied in Masson's trichrome staining for collagen fibers, Pap staining, and cytological polychromatic staining in histopathology. Light green SF yellowish also induces growth inhibition and local fibrosarcomas in rats and exerts mild pulmonary tumorigenicity in mice .

Dibromobimane is a Fluorescent dye and probe that can be used for the detection of intracellular reduced glutathione and the analysis of spatial proximity of closely adjacent cysteine thiol groups. Dibromobimane activates fluorescence through binding to thiol groups; its excitation/emission wavelengths are Ex/Em = 393/477 nm for glutathione detection, and Ex/Em = 385/477 nm for cysteine thiol cross-linking. Dibromobimane uses two equivalent bromomethyl groups to cross-link cysteine thiolates with a distance ranging from 3-6 Å. Dibromobimane can be applied to 96-well microplate-based high-throughput assays for labeling intracellular glutathione, and its fluorescence signal is normalized against nuclear staining results to eliminate the impact of cell density .

Wright's stain is a composite cell stain that mainly binds to intracellular nucleic acids, proteins and other components through thiazine dyes (such as methylene blue) and eosin. Wright's stain is pH-dependent (optimal pH 6.4-6.7) and achieves cell morphology resolution by differentially staining the cytoplasm and nucleus. Under alkaline conditions, thiazine dyes bind to nucleic acids to form purple, and acidic eosin binds to cytoplasmic proteins to form red, which can form contrasting cell morphological features. Wright's stain can clearly display the fine structures of blood cells and bone marrow cells (such as nuclear chromatin and granules) and quickly evaluate cell morphological abnormalities .

Aniline blue diammonium is a component of commonly used polychrome stains. Aniline blue diammonium is used to stain collagen fibers in tissue sections using Masson′s trichrome protocol for staining multiple components. Collagen is stained blue by this method. The dye is suitable for selective staining of callose in plant specimens and staining histones for assessing nuclear maturity. Aniline blue diammonium is used in Gomori′s one-step trichrome stain and Mallory′s connective tissue stain for tissue including kidney and intestine.

MCE Modified Van Gieson Staining Kit employs Celestine Blue and Mayer’s hematoxylin for nuclear staining, providing clearer and more stable nuclear visualization while facilitating longer preservation of stained sections. Ponceau S is used for collagen fiber staining, offering stable coloration and strong resistance to fading. This method enables effective differentiation between collagen fibers and muscle fibers, and can assist in distinguishing collagen fiber–derived tumors from myogenic tumors to a certain extent. It is also suitable for observing tissue or organ injury, repair processes, and the degree of fibrosis.

Nissl Staining Solution (Thionin Method) is a neural tissue staining solution with thionin as the core component, which stains Nissl bodies purplish blue and nuclear chromatin blue. Nissl Staining Solution (Thionin Method) relies on positively charged thionin molecules to specifically bind to the negatively charged nucleic acid components in the rough endoplasmic reticulum inside Nissl bodies, and achieves differential staining by regulating pH through a buffer system. Nissl Staining Solution (Thionin Method) has pH-dependent staining selectivity; it exhibits the highest staining specificity for neuronal Nissl bodies under pH 3.65 conditions, and can efficiently label glial processes under pH 4.6 conditions .
