AF488 C5 Maleimide, Single 5 isomer

| Description | Alexa Fluor 488 C5 Maleimide, Single 5 Isomer is the C5 maleimide derivative of the green fluorescent dye Alexa Fluor 488, with excitation/emission maxima of approximately 493/516 nm. The dye features a C5 carbon linker and a maleimide reactive group, allowing direct covalent conjugation with thiol (-SH) groups on proteins, phosphorothioate-modified oligonucleotides, or small-molecule ligands without additional activation. This enables efficient and specific labeling, making it widely used for bioimaging, fluorescent tracing, and quantitative analysis. |
