FITC Lysine Dextran
FITC-dextrans have now been used for 25 years for studying microcirculation or membrane permeability.
TdB Consultancy is now launching FITC Lysine Dextran products – dextran derivatives carrying both free primary amines and free carboxylates as well as the fluorescent dye Fluroescein (FITC). Lysine is a naturally occurring amino acid and popular moiety for conjugation and fixation in biochemistry and life sciences. FITC Lysine Dextran is supplied as a yellow to orange, water-soluble powder and is an environmentally friendly fluorescent aminodextran developed in order to meet an increasing demand from the scientific community for non-toxic, versatile polysaccharides. FITC-Lysine dextran is also known as Fluoro-emerald ® or fluoroemerald ®.
FITC Lysine dextran is a dextran polymer chain of various MW (see below) carrying the natural amino acid Lysine as a substituent. 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. Fluorescein is a bright dye that is used world-wide and absorbs at 493 nm and emits light at 520 nm.
Our high quality FITC Lysine Dextrans offer:
- Excellent MW distribution (Low Pd)
- Bright fluorescence
- Fixability in cells and tissue
- Easy conjugation to dyes or biomolecules
- Full water solubility and excellent stability in solution or on the shelf
