The VECTREX® matrix is optimized for immobilization of nucleic
acids. This matrix consists of particles of a highly cross-linked
sugar polymer that has a very large surface area and low nonspecific
binding for nucleic acids. Unlike agarose, which may
retain small molecules in its pores, the VECTREX®v particle will
retain molecules only through specific affinity interaction on
the surface of the particles. The VECTREX® matrix is dense and
sediments readily even without centrifugation.
