Acridine Orange hydrochloride is a cell-permeable fluorescent nucleic acid dye and lysosomal probe with a pKa of 9.65. Acridine Orange hydrochloride enters cells via passive diffusion, is protonated and accumulates in acidic lysosomes, and forms aggregates at high concentrations, producing orange-red fluorescence; when the lysosomal proton gradient or membrane integrity is impaired, Acridine Orange hydrochloride is released into the cytoplasm, green fluorescence increases and red fluorescence decreases, so it can be used to monitor lysosomal acidification status and changes in membrane permeability. Acridine Orange hydrochloride binds to nucleic acids through intercalation or electrostatic interactions, exhibiting mainly green fluorescence when bound to double-stranded DNA and mainly red fluorescence when bound to RNA or single-stranded DNA, and can be used for nucleic acid staining and differential DNA/RNA detection. The Ex/Em of Acridine Orange hydrochloride monomer is approximately 492/525 nm; when bound to double-stranded DNA it is approximately 488/520-524 nm, and when bound to RNA or single-stranded DNA it is approximately 457/630-650 nm .

Bromocresol green is a pH-sensitive triphenylmethane dye commonly used for the determination of protein and albumin in serum. Bromocresol green is a bio-based dye with a yellow-green to blue-green color. Bromocresol green turns yellow (λmax=435 nm, protonated form) when placed in acidic solution (e.g. pH=4.15), and turns blue in basic solution (λmax=615 nm, deprotonated form). Bromocresol green is widely used as a pH indicator in the field of biochemical analysis. In addition, Bromocresol green is also used to detect the concentration of molecules such as creatinine, and to judge the viability of cells .

4-(Dimethylamino) cinnamaldehyde is a staining agent that reacts with flavan-3-ols and Proanthocyanidins (HY-N0794) bearing meta-dihydroxyl or trihydroxyl phenol structures to form a green chromophore. In acidic media, 4-(Dimethylamino) cinnamaldehyde undergoes a condensation reaction with aromatic primary amines to produce colored and stable quinoid protonated Schiff base salts. 4-(Dimethylamino) cinnamaldehyde can be used to determine indole products of apotryptophanase and tryptophanase, as well as for the detection and analysis of Proanthocyanidins, with the absorbance detection wavelength of the calibration curve set at 640 nm .

OF-02 is an ionizable lipid for mRNA delivery and a key component of lipid nanoparticles (LNPs). OF-02 is protonated in the acidic endosomal environment to promote endosomal escape of mRNA and efficiently induce protein expression in target cells. OF-02 relies on the pH-responsive membrane fusion properties to form a complex with mRNA and destroy the endosomal membrane structure to achieve mRNA release in the cytoplasm. OF-02 is mainly used in the development of mRNA vaccines, gene editing, and protein replacement therapy[1][2][3].

TAPS is an aminosulfonate-based lysozyme stabilizer and connexin channel inhibitor. TAPS maintains the native structure of lysozyme in aqueous solution at pH 7.0 and significantly protects it from heat-induced denaturation. TAPS directly inhibits the activity of heteromeric connexin 32/connexin 26 channels (Cx32/Cx26) via its protonated form, and this inhibitory effect is dependent on the presence of connexin 26. TAPS reduces connexin channel-mediated solute exchange in a recombinant liposome system, resulting in a decreased degree of liposome density shift in transport-specific separation assays. TAPS is a critical compound for investigating the structure and function of connexin channels .

2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .

Endo-pH is a cell-permeable, pH-responsive fluorescent probe based on BODIPY, with a pKa of 5.08. When pH decreases from 7.32 to 4.97, Endo-pH undergoes protonation under acidic conditions, resulting in a 79-fold increase in fluorescence intensity at 786 nm. The detection wavelengths of its protonated form are Ex/Em=688/786 nm, while the absorption wavelength of its non-protonated form is 745 nm. Endo-pH can be used for staining late endosomes in live cells and determining the fusion time of late endosomes and lysosomes .

MSDH (O-Methyl-serine dodecylamide hydrochloride) is a lysosomotropic detergent that targets the lysosomal membrane. MSDH enters cells via endocytosis, accumulates in lysosomes and becomes protonated, forming physiological pH vesicles that dissociate at acidic pH, and acts as a micellar detergent. MSDH induces lysosomal membrane permeabilization, deacidification, release of cathepsin D/B and β-N-acetylglucosaminidase, and translocation of galectins to lysosomes. MSDH induces apoptosis, necrosis, caspase-3 activation, a decrease in mitochondrial transmembrane potential, and elevated p62/LC3BII levels. MSDH can be used in research on non-alcoholic steatohepatitis and head and neck squamous cell carcinoma .
