Cat. No.: HY-D2381
AF 488 maleimide is a thiol-reactive dye used to label SH groups of proteins, which can attach the AF 488 fluorophore to cysteine residue-containing proteins and peptides as well as other thiolated molecules. AF 488 maleimide enables real-time visualization of dynamic pilus extension and retraction in live bacterial cells via epifluorescence microscopy (Ex/Em = 470/520 nm) .

AF488 C5 Maleimide is a thiol-reactive Fluorescent dye used to label target proteins and bacterial structures. AF488 C5 Maleimide irreversibly forms covalent thioether conjugates with cysteine ​​thiol groups. AF488 C5 Maleimide stabilizes pre-formed globular low-molecular-weight Tau protein oligomers by blocking cysteine-dependent tau protein aggregation, allowing observation of the internalization process of tau protein oligomers into neuronal cells via confocal microscopy. AF488 C5 Maleimide can label cysteine-modified pili; the outer membrane permeability varies among different bacterial species, allowing imaging via epifluorescence microscopy using a FITC filter set .
