Hemoglobin Removal Kits


Hemoglobin Depletion For Erythrocyte Proteomics

  • Hemoglobin voids in flow-through, applicable to red cells, heavily hemolyzed serum, whole blood and dried blood spot (DBS) card
  • Low abundance protein and enzyme enrichment
  • Consumable, cost-effective
  • Mild elution maintains native structure with retained enzymatic, functional and bioactivities
  • Compatible with LC-MS, activity-probe profiling and virtually all proteomic analyses

2DE Comparison

2DE Comparison.
Red circles indicate the Hemoglobin subunits region. The HemoVoid™ eluate (bottom) has been severely depleted of Hemoglobin. The remainder of the red cell proteins are substantially enriched (visualized) and are better resolved in the HemoVoid™ eluate. Many more proteins are detectable after HemoVoid™ treatment with extensive proteome coverage across both dimensions.

HemogloBind™ Blood Card Kit

Hemoglobin Depletion and Protein Enrichment From Dried Blood Spots

  • Dried blood spots are useful for low volume analyses, and simple collection and transport
  • Protocols suitable for inexpensive whole blood card systems, no need for cell separation
  • Hemoglobin binding >90%, with 30-45 minute spin-filter format
  • Protocols based on ≤10 µl whole blood applied, but suspension format is flexible to most volumes
  • Blood proteins and enzymes are enriched for biomarker and proteomic investigations.
  • Removes hemoglobin from diverse species including human, sheep, bovine, goat, rat, mouse, etc.
  • High throughput easicly scalable.
