DQ-BSA-Red is a bovine serum albumin labeled with a red fluorescent dye that can be used to detect lysosomal activity. The excitation wavelength and emission wavelength of DQ-BSA-Red are 590 nm and 620 nm, respectively. The BSA molecule in DQ-BSA-Red is labeled with high concentration of red fluorescent dye in multiple sites, which shows high fluorescence self-inhibition. Once DQ-BSA-RED enters the lysosome, DQ-BSA is cleaved by lysosomal proteases, resulting in unquenched and released fluorescent fragments, emitting bright fluorescence. Inactivated lysosomes are unable to degrade the BSA protein and thus have a lower or even no fluorescent signal .

Synonyms: 6-(p-Tolylamino)naphthalene-2-sulfonate sodium
TNS (6-(p-Tolylamino) naphthalene-2-sulfonate) sodium is a fluorescent probe used to detect the conformational state of proteins. TNS sodium binds to the central hydrophobic calyx of β-lactoglobulin (β-LG) to form a 1:1 complex, which stabilizes the folded conformation of β-LG. TNS sodium shows weak fluorescent signals in aqueous solution, but its fluorescence intensity increases significantly upon binding to the hydrophobic domains of proteins, with the maximum excitation wavelength and maximum emission wavelength located at 321 nm and 446 nm, respectively .

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 .

Ibetazol is a Importin β1 (KPNB1) inhibitor and nucleocytoplasmic transport disruptor. Ibetazol binds covalently to Cys585 of Importin β1, blocks both Importin β1-mediated direct transport and Importin α-dependent nuclear import processes, without affecting transport mediated by other nucleocytoplasmic transport proteins. Ibetazol induces cytoplasmic accumulation of Importin α1, and inhibits nuclear import of substrates carrying nuclear localization signals (NLS), including the NLS-cMyc reporter gene, RelA/p65 and SREBP1. Ibetazol triggers spindle malformation and chromosome misalignment by disrupting the mitotic function of Importin β1. Ibetazol inhibits the proliferation of cells expressing wild-type Importin β1. Ibetazol has a high activity-cytotoxicity window, lacks intrinsic fluorescence, and acts rapidly on nucleocytoplasmic transport processes. Ibetazol serves as a tool compound for investigating nuclear import processes specifically mediated by Importin β1 .

CO probe 1 (probe 2) is a highly efficient fluorescent CO probe (Ex=493 nm) with an allyl ether reaction site. In the presence of PdCl₂, CO reduces Pd 2+ to Pd 0, triggering a Tsuji-Trost reaction that removes the allyl protecting group, releases fluorescein, and generates a significant fluorescence signal. CO probe 1 has high selectivity, rapid response (fluorescence enhancement of 150 times within 20 minutes), and low cytotoxicity, and can be used for real-time imaging of CO in living cells. CO probe 1 may be used to study pathological mechanisms involving CO signaling regulation, such as inflammation, vascular disease, or cancer .

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].
