    Ponceau S, BS

    acid Red 112, BS

    		 Biochemical Assay Reagents Others
    Both Ponceau S and Ponceau BS are synthetic dyes commonly used in biological research. They are commonly used as protein stains to visualize proteins in western blots and other protein detection analyses. Ponceau S is a red dye, while Ponceau BS is a blue shade of the same dye. Both dyes bind to positively charged amino acid residues in proteins for easy visualization. However, Ponceau S is more commonly used due to its higher sensitivity.

    Bathophenanthroline

    		Fluorescent Dye Others
    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].

    PTPA-QM

    		Fluorescent Dye Amyloid-β Neurological Disease
    PTPA-QM is a low-cytotoxicity Aβ protein probe that can be used for live-cell imaging and tissue section staining (Lys. Ex/Em = 385/615 nm). PTPA-QM can intercalate into the β-sheet layered structure of β-amyloid fibrils, form intermolecular interactions with amino acid residues, restrict intramolecular rotation and trigger fluorescence activation for imaging purposes. PTPA-QM is applicable to Alzheimer's disease-related research. Maximum excitation/emission wavelength: 448/605 nm .

    RADA

    		Bacterial Infection
    RADA is a fluorescent D-amino acid (FDAA) with high photostability and thermostability, which emits yellow-to-orange fluorescence. RADA shows low outer membrane permeability in wild-type Gram-negative Escherichia coli, but it targets penicillin-binding proteins and L,D-transpeptidases, mimics the interaction between acyl acceptors and enzyme intermediates, and integrates into peptidoglycan during biosynthesis. As a peptidoglycan labeling reagent, RADA metabolically integrates into the nascent peptidoglycan of live bacterial cells, labels the peptidoglycan at the poles and lateral walls of mycobacteria, and enables visualization of peptidoglycan synthesis and remodeling processes. RADA serves as a non-specific stain for fixed cells, is non-toxic to bacterial cells, and its red-shifted excitation/emission spectra reduce phototoxicity. RADA also supports virtual pulse-chase labeling experiments and stochastic optical reconstruction microscopy for sub-diffraction-limited imaging of bacterial cell walls .
