Cat. No.: HY-K3120
MCE Serum/Plasma Exosome Isolation and Purification Kit (Magnetic Beads) utilizes a magnetic bead-based method for the isolation and purification of exosomes. The underlying principle is based on the charge-dependent interaction between exosomes and functional polymers on the surface of the magnetic beads under an optimized buffer system, enabling selective adsorption of exosomes. Subsequent adjustment of the ionic strength and pH of the buffer promotes the gentle dissociation of exosomes from the magnetic beads, thereby enabling efficient exosome isolation and purification while maintaining high vesicle integrity and low impurity carryover.
