Rapid labeling and purification kits

Total hands-on time: 10 minutes, including purification.

FluoroSpin Protein Labeling and Purification Kits are designed for precision labeling of antibodies, enzymes or proteins having a molecular weight greater than 25 kDa. Labeling is accomplished using the reactive N-hydroxy-succinimidyl ester (NHS) of a fluorescent dye.

A strong, covalent amide linkage is made between the dye and protein lysine groups. These bonds provide superior stability and with lower side reactions compared to isothiocyanate coupling.

Rapid and efficient purification is accomplished with pre-hydrated CentriPure MINI columns (included).

A wide variety of fluorescent markers covering the complete emission spectrum from 300 to over 1000 nm are currently available from emp BIOTECH. If you do not see what you are looking for, please contact us. We provide expert technical assistance and support and look forward to hearing from you.
