Description
CD44 is a ubiquitously expressed receptor for hyaluronan and exerts control over cell growth, migration, and tumor progression. With variable N and O-glycosylation and splicing within the stalk, CD44 can range from 80 to 200 kDa. CD44 binds hyaluronan and other ligands within the extracellular matrix and can function as a platform for growth factors and metalloproteinases. It can function as a co-receptor that modifies activity of receptors including Met and the ErbB family tyrosine kinases. The intracellular domain of CD44 links the plasma membrane to the actin cytoskeleton via the ERM proteins, Ezrin, Radixin and Moesin. MagCellect products are designed for the isolation of cells in a liquid phase. MagCellect technology is based on the use of ferrofluids or magnetic nanoparticles that have no magnetic memory (superparamagnetic) and behave like colloidal particles. This feature allows the ferrofluids to remain in solution without the need for mixing and additionally allows for efficient diffusion kinetics during the binding reaction. The proprietary manufacturing technology of MagCellect( ferrofluids generates particles with higher ligand binding capacity per mass compared to many other larger diameter magnetic particles.
