Poly-electrolytesare polymers with repeating units of stationary charges.AlbuSorb™comes from a class of solid-phase, or surface-based, elastomericpoly-electrolytic surfaces that bind proteins through an empiricallyderived chemistry combining elements of polymer composition,cross-linking architecture and charge properties. AlbuSorb™combines with an optimized immobilized Protein A to create AlbuSorb™PLUS.

Unlikeimmuno-affinity, the surfaces utilized are disposable eliminatingcycle to cycle variance and cross-contamination. AlbuSorb™PLUSis supplied as a powder. Simply weigh, centrifuge and/or filter, andrecover the {albumin + Immunoglobulin} - depleted serum in thesupernatant.
