    Fluorescein-5-maleimide 75350-46-8 99.48%
    Fluorescein-5-maleimide (N-(5-Fluoresceinyl)maleimide) is a fluorescent dye. Fluorescein-5-maleimide can be used to detect the redox state of thiols in eukaryotic cells. Fluorescein-5-maleimide can label peptides and is used to detect negatively charged nanoparticles. Fluorescein-5-maleimide can also label actin to explore its interaction with cardiac myosin-binding protein C (cMyBP-C), which helps in developing small molecule modulators for heart failure. Fluorescein-5-maleimide can screen mutant proteins that contain cysteine residues. The excitation wavelength of Fluorescein-5-maleimide is 494 nm, and the emission wavelength is 519 nm.

    Vari Fluor 488-Streptavidin
    Vari Fluor 488-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=490 nm/515 nm.

    BC-GLA-NHS
    BC-GLA-NHS (CLIP-GLA-NHS) is a NHS-labeled CLIP tag, which is an amine-reactive crosslinker and can achieve site-specific protein labeling. The NHS ester of BC-GLA-NHS reacts with the primary amine of the target molecule (such as antibodies, quantum dots) in a pH 7.5-8.5 buffer solution to form a stable amide bond. After coupling, the BC molecule undergoes a nucleophilic substitution reaction with the active site (Cys) of the CLIP-tagged fusion protein, releasing benzylcytosine and forming an irreversible thioether bond, achieving covalent labeling. BC-GLA-NHS can be used for click chemistry labeling.
