Lysine-dextran

Lysine-dextran

Lysine-dextrans are dextran derivatives carrying both free primary amines and free carboxylates. Lysine is naturally occurring amino acid and a popular moiety for conjugation and fixation in biochemistry and life sciences. All batches are checked for molecular weight, degree of substitution and loss on drying. TdB labs produce lysine-dextran from 4 kDa to 500 kDa. Lysine-dextran is supplied as a white powder.

Our high-quality lysine-dextran offers:

  • Excellent MW distribution (Low Pd)
  • High quality, white and pure powder formulations
  • Good stability and performance
  • Fixability in cells and tissue
  • Easy conjugation to dyes or biomolecules
  • Full water solubility

Structure
Lysine-dextrans are well-characterised dextran fractions derived from Leuconostoc mesenteroides to which lysine is coupled.

Storage and stability
Lysine-dextran is stable for more than 6 years when stored dry in well-sealed containers at ambient temperature.

Solubility
Lysine-dextran dissolves readily in water.

Application
Lysine-dextran can be labeled with dyes or biomolecules under mild conditions and fixes well in cells and tissue when treated with formaldehyde or glutaraldehyde. Read more about application here.
