nanomag¢ç -CLD ÀÚ¼ºÀÔÀÚ CrossLinked Dextran |
Biopolymer particles |
Crosslinked magnetic dextran nanoparticles (nanomag¢ç -CLD)
- prepared via the core-shell method with a core of magnetite and a dextran shell
- available with particle diameters of 300 nm and 500 nm
- consist of 80-90% (w/w) magnetite in a matrix of crosslinked dextran (40.000 D) and can -easily be separated with a conventional permanent magnet
- designed with NH2, COOH, PEG-COOH or maleimide groups for the covalent binding of proteins, antibodies or other molecules
- available with covalently bound streptavidin (or other proteins on request)
