1-Pyrenebutyric acid is a pyrene-based fluorescent probe compound. The fluorescence lifetime of 1-Pyrenebutyric acid is quenched by molecular oxygen and intracellular ROS, thus it serves as a fluorescent probe for detecting ROS and oxygen concentration through fluorescence lifetime measurements. 1-Pyrenebutyric acid undergoes electrostatic interactions with arginine-rich peptides, increasing their net hydrophobicity, promoting their direct translocation across lipid bilayers, and enhancing cytosolic delivery. 1-Pyrenebutyric acid is used for intracellular reactive oxygen species detection and research related to arginine-rich peptide-mediated cytosolic delivery .

Bathophenanthrolinedisulfonic acid disodium is an iron ion chelator that serves as a colorimetric reagent for iron ion detection. Bathophenanthrolinedisulfonic acid disodium forms stable, strong complexes with Fe 2+ and Fe 3+, and each complex exhibits reversible redox behavior. Bathophenanthrolinedisulfonic acid disodium can act as a ligand to form water-soluble ruthenium catalysts, which promote the hydrogenation of the ketone group in levulinic acid to produce γ-valerolactone. When Bathophenanthrolinedisulfonic acid disodium and its iron complex are incorporated into a polymer-modified electrode, rapid color change from red to transparent occurs during potential cycling .

MCE DAB Peroxidase Substrate Kit (Brown) is a chromogenic reagent kit based on the HRP-catalyzed oxidation of DAB. It is suitable for staining and chromogenic detection in immunohistochemistry, immunocytochemistry, in situ hybridization, Western blotting, and other applications using cell or tissue samples. The resulting insoluble brown precipitate provides clear localization and stable visualization of target signals, facilitating direct observation and analysis. Following DAB development, counterstaining can be performed according to experimental requirements. For example, ethanol-soluble dyes can be used for subsequent counterstaining to facilitate the visualization and analysis of cellular or tissue morphology.

DC271 is a RAR agonist and synthetic retinoid that binds to the retinoid-binding site of cellular retinoic acid-binding protein II (CRBP-II). DC271 exhibits solvatochromic fluorescence properties: it produces intense blue-shifted emission in nonpolar environments and weak red-shifted emission in polar environments, and its severe fluorescence quenching in aqueous solutions can be reversed by embedding in the hydrophobic retinoid-binding protein pocket. DC271 enables direct detection of the binding between unlabeled compounds and related retinoid-binding proteins via fluorescence competition assays (Ex/Em = 355 nm/460 nm) .
