MagPlex-TAG™ Microspheres

MagPlex-TAG™ Microspheres are oligonucleotide-coupled polystyrene microparticles, or “beads,” that have been dyed into spectrally distinct sets, or “regions,” allowing them to be individually identified by an xMAP® instrument. Each of these uniquely color coded beads has a unique 24 base DNA sequence, called an “anti-TAG,” covalently coupled to its surface. These beads enable you to quickly and easily design custom bead arrays simply by adding a complementary “TAG” sequence to your primers or probes of interest and hybridizing those primers or probes to the anti-TAG sequences on the addressable microsphere.

MagPlex-TAG™ Microspheres are magnetic, allowing them to be easily separated from solution with the use of a magnetic separator. This improves percent recovery during handling and wash steps and facilitates assay automation.

Additionally, MagPlex-TAG Microspheres are compatible with all xMAP® instruments, including the MAGPIX® system. MAGPIX is simple and easy to use, has a small footprint, and is the most economical multiplex instrument on the market.

All microspheres are general use components for further manufacture of xMAP bioassays. MagPlex-TAG Microspheres are available at a concentration of 2.5 million beads/mL and can be ordered in 1 mL vial sizes only. Please contact Luminex to inquire about custom vial sizes.

MagPlex-MixTAG80 Microspheres

The MagPlex®-MixTAG80 product is a mixture of 80 (Group A & B) MagPlex-TAG Microsphere regions. This product is intended to facilitate the devel­opment of nucleic acid arrays with 80 or less targets. As each microsphere reacts only to nucleotides strands containing their specific complementary TAG sequence, unused regions in assays of less than 80 targets will not be detected by the instrument and not included in the resulting data set.

The MagPlex-MixTAG80 product is intended for Luminex® 100/200™ and FLEXMAP 3D® instruments running xPONENT® software only. Although the microsphere mixture can be used with the MAGPIX instrument, MAGPIX will only detect 50 of the 80 regions in the mixture.

IMPORTANT: MagPlex-TAG microspheres require the use of xPONENT software.
