HemoVoid™ LC-MS On-Bead For RBC Proteomics 

HemoVoid™ LC-MS On-Bead is an hemoglobin depletion and enzymatic proteolytic digestion reagent kit. It

removes hemoglobin from serum and plasma samples while concentrating low abundance proteins on the

beads. It is ideal for applications involving LC-MS discovery and targeted proteomics.

The HemoVoid™ beads are derived from a silica-based library of individual mixed-mode polymeric ligands.

The library was designed to facilitate weak binding of proteins, allowing for progressive enrichment of the low

abundance proteome, with specialized voiding properties empirically derived. The HemoVoid™ beads have

been adapted to a protocol specifically designed for LC-MS applications whereby the low

abundanceproteome adsorbed to the bead is proteolytically degraded to its peptide constituents. In this way

HemoVoid™ LC-MS On-Bead integrates low abundance enrichment, with Trypsin (or other suitable

protease) on-bead digestion, in a simple, highly efficient and seamless workflow for LC-MS discovery and

quantitative analyses. 

Features

• Hemoglobin voids in flow-through >95%, with <30 minute bind/wash microfuge protocol

• Low abundance enrichment and proteolytic trypsin digestion on the same bead.

• Consumable, cost-effective, no column regeneration or cross-contamination

• Species agnostic; human, rat, mouse, goat, sheep, porcine and bovine sera have been tested

• Trypsin digestion on the bead

• Seamless workflows and unique proteolytic efficiencies

  - No in-gel digests, no solution digests, no C18 desalting, more consistent, reproducible results

  - Compatibility with quantitative label (i.e., iTRAQ) and label-free LC-MS methods
