| 产品介绍 |
Aladdin® 594 is a bright red dye. Used for stable signal generation in imaging and flow cytometry, Aladdin® 594 dye is water soluble and pH-insensitive from pH 4 to pH 10. In addition to reactive dye formulations, we offer Aladdin® 594 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection. The NHS ester (or succinimidyl ester) of Aladdin® 594 is the most popular tool for conjugating this dye to a protein or antibody. NHS esters can be used to label to the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting Aladdin® conjugate will exhibit brighter fluorescence and greater photostability than the conjugates of other spectrally similar fluorophores. Detailed information about this Aladdin® NHS ester: Fluorophore label: Aladdin® 594 dye Reactive group: NHS ester Reactivity: Primary amines on proteins and ligands, amine-modified oligonucleotides Ex/Em of the conjugate: 590/617 nm Extinction coefficient: 92,000 cm-1M-1 Molecular weight: 819.8 The Aladdin® NHS ester is typically dissolved in high-quality anhydrous dimethylformamide (DMF) or dimethylsulfoxide (DMSO), and the reaction is carried out in 0.1–0.2 M sodium bicarbonate buffer, pH 8.3, at room temperature for 1 hour. Because the pKa of the terminal amine is lower than that of the lysine epsilon-amino group, you may achieve more selective labeling of the amine terminus using a buffer closer to neutral pH. |
