产品描述 | Alexa fluor 647 maleimide is a water-soluble fluorescent dye that maintains stability under a broad range of physiological conditions. Alexa fluor 647 maleimide facilitates the covalent attachment of fluorescent groups to proteins through selective reaction with thiol groups, thereby enabling precise labeling. This labeling method offers both high sensitivity and specificity, allowing detection of proteins at very low concentrations. Alexa fluor 647 maleimide is widely applied in the study of protein expression and localization, and it can also be conjugated to antibodies for labeling cell surface antigens or specific proteins within tissues [Ex/Em(nm)=651/671]. |
