Flamma® 552 Vinylsulfone

Product description: Chemical. Formula: C38H51N3O9S3. MW: 790.02. Synthetic. Flamma®552 is an orange fluorescent dye induced from cyanine structure and has a maximum value of Ex/Em at 550nm/565nm, and it can be also used for 532, 543, 546, 555, 568nm laser lines. Flamma®552 has a similar optical spectrum to Alexa Fluor®555 and CY3. Flamma®552 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): 550 / 565 nm. Spectrally similar dyes: Alexa Fluor®555, CY®3, DyLight®549, ATTO550, CF™555. Extinction coefficient: 150,000 cm-1M-1. CF280: 0.07.
