PreCap Oligo(dT) Phmac Beads is a polymer microspheres with Oligo(dT)25 ligands covalently bound on its surface. The average particle size of PreCap Oligo(dT) Phmac Beads is 60μm. The surface is functionalized with poly(dT) and allows capture of mRNA though base pairing with the mRNA polyA tail, mRNA can be purified directly from the sample, which greatly simplifies the process of mRNA capture. The product withstands high salt, pH and temperature, is simple to use, and does not require the use of any flammable, toxic reagents.
