New Magnetic Bead Multiplex Assays

Millipore’s new suite of multiplex assays use magnetic beads for more consistent results and automation compatibility. Designed for use with Luminex® xMAP® technology, these new MILLIPLEX® MAG kits complement Millipore’s broad selection of non-magnetic multiplex assays and enable researchers to choose the format they prefer.

MILLIPLEX MAG kits include microspheres embedded with superparamagnetic particles. Once bound to the protein of interest, the microspheres can be magnetically separated. This makes sample preparation easier and eliminates the risk of sample loss, clogs, or leaks. The new kits also reduce non-specific binding, which results in lower, more consistent coefficients of variation (CVs). To date, seven MILLIPLEX MAG kits have been released, including kits for cytokine and chemokine research and metabolic disease research. A significant portion of the existing MILLIPLEX line will be available in both magnetic and nonmagnetic formats by the end of 2010.
