Flamma® 496 Vinylsulfone

Product description: Chemical. Formula: C25H19F2NO8S. MW: 531.48. Synthetic. Flamma®496 is a fluorescent dye induced from Fluorescein structure and has a maximum value of Ex/Em at 496nm/516nm. Even though it is optically similar to FAM, it has features that are excellent light stability and better brightness compared to FAM. Flamma®496 Vinylsulfone is an independent labeling functional group of BioActs. Depending on the characteristics of Vinylsulfone, it stably reacts to primary amine (-NH2). Therefore, it can stably label protein or peptide in aqueous solution, and it is easy to adjust labeling efficiency of reactants according to the user’s purpose due to its moderate reaction rate. In addition, this product can be refrigerated in the form of dissolved in water. Excitation ? Emission (nm): 496 / 516 nm. Spectrally similar dyes: FITC, Fluorescein. Extinction coefficient: 82,000 cm-1M-1. CF280: 0.19.
