Biotech Support Group

Biotech Support Group provide separation and enrichment tools for the preparation of samples for proteomics and genomics.

Proteomic & Genomic Sample Prep and Enrichment

The surface chemistries of Biotech Support Group kits focus on selective protein binding and ensure functional and structural properties of samples are retained. This is essential for functional studies and for enrichment of enzyme biomarkers – allowing for better data quality for all downstream proteomic and biomarker analyses.


  • Consumable use, not derived from biologicals
  • Functional integrity, suitable for functional and chemical proteomics
  • On-bead digestion, improves performance and workflow
  • Strategies for both enrichment of low abundance proteomes, or depletion of high abundance proteins.

The BSG Advantage

All BSG products have the following common features and advantages:

1. Consumable

  • No specialised instruments or HPLC required
  • Economical surface chemistries, not derived from biologicals
  • No regeneration, therefore no prep to prep variability
  • Simple & fast protocols for microfuge binding/washing and elution.

2. Diverse Strategies for Enrichment/Depletion

  • Products support strategies for both enrichment of low abundance proteomes, or depletion of high abundance proteins
  • Species agnostic, not derived from biologicals.
High Abundance Depletion + Digestion Efficiency + Simple Workflow = Better LC-MS Output

3. On-Bead Digestion: Efficient Workflows and Improved Data

  • Simple, reproducible workflows
  • Equivalent or better than in-solution digestion
  • Seamless to LC-MS, no desalting or C18 separations
  • Unique proteolytic efficiencies

4. Functional Integrity Maintained Throughout All Separations

  • Mild buffer conditions maintains native structure with retained enzymatic, functional & bio-activities
  • Supports enzyme biomarker assays
  • Functional & chemical proteomics
  • Structural & activity-probe proteomics
  • Top-down & Array Bridge PEP proteomics
