Seta-555-NHS (K8-3335) is highly hydrophilic, amine-reactive fluorescent label containing one reactive NHS-ester group with almost identical absorption and emission as Cy3™ or Alexa Fluor™ 555 and can therefore be used with these filter sets. It combines high photostability and brightness.
Applications
Covalent labeling of proteins, amino-modified DNA and amino-modified oligonucleotides
Advantages
Perfectly suited for excitation with the 532-nm laser
About twice the brightness of Cy3
Good aqueous solubility: this label does not alter the solubility of the protein conjugate
Low molecular weight: Seta-555 does not add substantial mass to the conjugates
Photostability: Higher photostability as compared to Alexa Fluor™ 555 or Cy3
Ideal for non-radioactive labeling of proteins, amino-modified DNA probes and amino-modified oligonucleotides
