Sera-Mag Oligo(dT)-Coated Magnetic Particles enable mRNA isolation and extraction for applications such as RT-PCR, cDNA library construction, cDNA microarrays, affinity purification, primer extension, and subtractive hybridisation.

• Encapsulation means no exposed iron and minimised interference with downstream enzymatic applications
• Covalently bound oligo(dT)14 prevents leaching from the particle surface
• Very high, specific poly A+ binding capacity ensures maximum extraction of mRNA
• Fast reaction kinetics increase throughput and precision, also enabling faster movement through viscous solutions
• Uniform, nominal 1μm diameter provides high surface area and excellent lot-to-lot reproducibility
• Also available as custom-manufactured magnetic beads
