Oligo d(T)25 is covalently coupled to 1 μm superparamagnetic particle through a linkage that is stable and leak resistant over a wide pH range, thereby permitting the small-scale isolation of mRNA from crude cell lysates and tissue. The isolation occurs through the hybridization of covalently coupled oligo d(T)25 to the poly(A) region present in most eukaryotic mRNAs.
• Allows for direct mRNA isolation following lysis and second-round purification of previously isolated total RNA
• The magnetic separation technology is scalable and permits elution of intact mRNA in small volumes, thereby eliminating the need for precipitation of the isolated mRNA
• Beads can be reused up to three times
• The isolated mRNA can either be eluted or the bound d(T)25 can be used as a primer in a first-strand cDNA reaction
