Sudan IV is an agonist of the aryl hydrocarbon receptor (AhR) that activates downstream signaling pathways and induces CYP1A1 expression. Sudan IV promotes CYP1A1 gene transcription by activating AhR-ARNT heterodimers and binding to exogenous response elements (XREs) on DNA, thereby enhancing drug metabolizing enzyme activity. Sudan IV can be used to study the toxicity mechanisms of industrial dyes and the effects of interactions with serum proteins (such as bovine serum albumin (BSA)) on their distribution in vivo. Sudan IV is a fat-soluble diazo dye that can be used to stain lipids, triglycerides, and lipoproteins on frozen sections .

Pararosaniline hydrochloride (Basic red 9) is a pH-responsive basic dye, as a biological stain to track certain proteins. The pH of the acidified Pararosaniline hydrochloride reagent has a significant effect on the color and the maximum absorption wavelength (λmax) of the reaction system, with its optimum pH 0.48 and a λmax at 549 nm. Pararosaniline hydrochloride is also a strong modifier of RNA splicing. Pararosaniline hydrochloride has been used in the analysis of SO2 and formaldehyde and staining of bacteria or other organisms. Pararosaniline hydrochloride is extensively used in industries like textile, printing, paper, cosmetic, and leather .

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 .

Bathophenanthroline is a nitrogen-containing organic ligand that can form stable complexes with transition metal ions such as Ru 2+. In proteomics, Bathophenanthroline is often used for in-gel protein staining. The negatively charged sulfonic acid groups of Bathophenanthroline interact electrostatically with the positively charged amino acid residues of proteins, thereby achieving specific binding to proteins and enhancing the fluorescent signal of detection. Bathophenanthroline can be used for protein separation and detection in SDS-PAGE gels in the field of proteomics, as well as other fluorescence studies[1]. Ex/Em=532 nm/610 nm[1].

Vari Fluor 647-Streptavidin is a dye marker of Vari Fluor-streptavidin consisting of labeling streptavidin with a Vari Fluor series of fluorescent probes. Streptavidin is a high-affinity tetramer protein, each tetramer consisting of four identical streptavidin subunits. Streptavidin binds to biotin specifically via a reversible non-covalent effect. Streptavidin can achieve rapid and efficient detection of biotin markers, and is often used in immunofluorescence (IF), enzyme-linked immunosorbent assay (ELISA), immunohistochemical staining (IFH), in situ hybridization (ISH) and other experiments. Ex/Em=650 nm/665 nm.

Basic blue 26 (Victoria blue B) is a synthetic cationic dye belonging to the class of triarylmethane dyes. It has a bright blue color and is commonly used as a colorant for a variety of applications, including textiles, paper and leather. Basic Blue 26 is also used as a biological stain for DNA and protein detection in laboratories. Due to its ability to bind negatively charged materials, it can be used as an indicator of the presence of specific molecules in biological samples. However, Basic blue 26 has been reported to have potentially harmful effects on human health and the environment and its use is regulated in some countries. Proper handling and disposal procedures are necessary to minimize its impact on the environment.

CFDA-SE (solution) is a fluorescent dye that can penetrate the cell membrane. It can react with the free amine group in the cytoskeleton protein inside the cell, and finally form a protein complex with fluorescence. After entering the cell, CFDA-SE locates in the cell membrane, cytoplasm and nucleus, and the fluorescence staining is strongest in the nucleus . CFDA-SE dye can be uniformly inherited by the cells with cell division and proliferation, and its attenuation is proportional to the number of cell divisions. This phenomenon can be detected and analyzed by flow cytometry under the excitation light of 488 nm, and can be used to detect the proliferation of cells .
