  • Oligo d(T)25 Magnetic Beads


    Oligo d(T)25 Magnetic Beads are a 1 μm polymer based affinity matrix for 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 mRNA. Applications include 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 eliminating the need for precipitation of the isolated mRNA. Beads can be reused up to three times and the researcher has the option of eluting the isolated mRNA or using the bound d(T)25 as a primer in a first-strand cDNA reaction.
