Characteristic

  • Fast:  The whole process takes only 90 min.
  • Convenient: : The dye has been activated and can be used directly. Filtration
    tube desalts without dialysis.
  • Flexible use: It can be used for both micro-labeling and large-scale labeling,
    0.1-1 mg proteins can be labeled each time.
  • Water solubility: Elab Fluor® 488 in this kit is water-soluble, and the
    fluorescence characteristics of the dye can be well measured and maintained
    in aqueous buffer.

 

Essential Information

Excitation/Absorption maximum (nm) 495
Emission maximum (nm)   519
Molar extinction coefficient ε (L⋅mol−1⋅cm−1) 71800
Correction coefficient of 280nm(CF280)  0.1

 

Labeling Principle

Within a certain pH range, Elab Fluor® 488 specifically reacts with primary amino groups (N-terminal and lysine residue side chains) to form a stable amide bond, so as to realize the coupling of Elab Fluor® 488 with protein.

 

Materials Not Supplied

  1. Pipettor and tips (0.5-10μL, 2-20μL, 20-200μL, 200-1000μL).
  2. Ultraviolet spectrophotometer or nanodrop or multifunctional microplate reader.
  3. 37°C incubator.
  4. Centrifuge (centrifugal force up to 12,000×g).

 

Storage

The unopened kit can be stored at 2~8°C for 1 year, and the dissolved Elab Fluor® 488 can be stored at -20°C or -80°C for 1 week.

 

Notes
  1. Please select the appropriate kit according to the molecular weight of the protein to be labeled. The kit provides a 10 KD Filtration tube.
  2. Elab Fluor® 488 is susceptible to moisture hydrolysis failure, and should be stored at -20°C or -80°C with the desiccant. In order to prevent water vapor from condensing into the dye, it is necessary to equilibrate the dye to room before the experiment.
  3. The kit can also be used to label other proteins containing free amino groups. The specific labeling ratio is determined according to the number of available amino groups in the marker or set different molar ratios for labeling.
