Poly-electrolytes are polymers with repeating units of stationary charges. AlbuSorb™ comes from a class of solid-phase, or bead-based, elastomeric poly-electrolytic beads that bind proteins through an empirically derived chemistry combining elements of polymer composition, cross-linking architecture and charge properties. As with bio-polymers like DNA and Heparin, governing their reactivity is the spatial presentation of the electrostatic groups along a flexible polymer chain. Unlike immuno-affinity, the surfaces utilized are disposable eliminating cycle to cycle variance and cross-contamination. AlbuSorb™ is supplied as a dry powder. Simply weigh, centrifuge and/or filter, and recover the albumin depleted serum in the supernatant. 10 preps AlbuSorb™ beads, 10 preps AlbuSorb™ suspension
