[Biotech Support Group] Albumin + IgG depletion from serum or plasma


AlbuSorb™ PLUS


Albumin + IgG depletion from serum or plasma


  •  >400 μg total serum protein mass (> 85% Albumin, >85% IgG depleted) from 25 μl serum prep
  •  Affinity-type equivalence, virtually no cross-reactivity with other proteins
  •  Disposable, no column regeneration or cross-contamination
  •  Combines unique bead technology, not based on Blue-dye affinity, with optimized Protein A
  •  Mild conditions maintains structural integrity and simple transfer to secondary analysis
  •  Suitable for immunoassay, Western blot, 1 & 2D Electrophoresis, enzyme assay, LC-MS
  •  Tested species include human, sheep, bovine, rabbit, mouse, rat


Poly-electrolytes are polymers with repeating units of stationary charges. AlbuSorb™ comes from a class of

solid-phase, or surface-based, elastomeric poly-electrolytic surfaces that bind proteins through an

empirically derived chemistry combining elements of polymer composition, cross-linking architecture and

charge properties. AlbuSorb™ combines with an optimized immobilized Protein A to create AlbuSorb™PLUS.


Unlike immuno-affinity, the surfaces utilized are disposable eliminating cycle to cycle variance and cross-

contamination. AlbuSorb™ PLUS is supplied as a powder. Simply weigh, centrifuge and/or filter, and recover

the {albumin + Immunoglobulin} - depleted serum in the supernatant.
