What Are Supermacroporous Polymer Microspheres?

Supermacroporous polymer microspheres are advanced chromatography media featuring interconnected macropores ranging from 100 nm to 400 nm. These pores are large enough to allow intact virus particles and viral-like particles (VLPs) to enter the bead interior and bind to ion exchange functional groups throughout the entire volume of the particle — not just on the surface.

Five Key Advantages of Supermacroporous Polymer Microspheres

Engineered to overcome the limitations of conventional chromatography media for biologics purification.

01

Full Pore Accessibility for Viruses & Large Particles

Large molecules or viral particles can easily enter the pores for binding. The supermacroporous structure with pores from 100–400 nm allows intact viral vectors, VLPs, and protein complexes to access the entire internal surface area, not just the outer shell.

02

10× Loading Capacity vs. Agarose Media

The load capacity is more than 10 times that of conventional agarose media and twice that of conventional polymer media. This dramatic increase in binding capacity reduces column volume requirements and process time per batch.

03

Preserves Structural Integrity of Target Proteins

It can maintain the integrity of the structure of large molecular proteins, obtaining high yield and high activity of the target protein. Gentle binding kinetics and optimized ligand density minimize denaturation and aggregation during capture.

04

Low Non-Specific Adsorption, High Mechanization

After hydrophilic modification of the microsphere surface and the bonding of ion exchange groups, non-specific adsorption is low, and the degree of mechanization is high. This ensures reproducible results and scalable manufacturing processes.

05

Fast Mass Transfer at High Flow Rates

The molecular mass transfer rate is fast, and better separation can be achieved at higher flow rates. With flow rates up to 1,200 cm/h for PS-DVB series, these media deliver productivity gains without sacrificing resolution or binding capacity.

Purify gene therapy delivery vectors at scale with chromatography media designed to handle the full size range of viral and non-viral vectors while maintaining biological activity.

Frequently Asked Questions

Common questions about supermacroporous polymer chromatography media.

What are supermacroporous polymer microspheres?

Supermacroporous polymer microspheres are advanced chromatography media featuring interconnected macropores ranging from 100 nm to 400 nm. These pores are large enough to allow intact virus particles and viral-like particles (VLPs) to enter and bind to ion exchange functional groups within the pores, delivering over 10 times the loading capacity of conventional agarose media. Biovanix produces these media in two matrix platforms: PS-DVB and PMMA.

What is the difference between PS-DVB and PMMA microspheres?

PS-DVB (polystyrene-divinylbenzene) microspheres offer superior chemical resistance, wider pH stability (1–12), and higher pressure tolerance (up to 8.0 MPa), making them ideal for aggressive cleaning and high-flow applications. PMMA (polymethyl methacrylate) microspheres provide biocompatible surfaces suited for sensitive biological samples and moderate operating conditions up to 1.0 MPa.

How do l choose the right pore size for virus purification?

Select pore size based on the diameter of your target particle: S series (100 nm) for small viruses and proteins, M series (100–150 nm) for medium-sized viral vectors such as AAV and lentivirus, G series (150–300 nm) for large VLPs and enveloped viruses, and V series (300–400 nm) for the largest viral particles such as baculoviruses and certain plant viruses.

What is the loading capacity of supermacroporous polymer microspheres?

Supermacroporous polymer microspheres deliver loading capacities exceeding 10 times that of conventional agarose media and twice that of standard polymer media. For example, PS-DVB Poly15 SP achieves 80 mg Lys/mL capacity, while PMMA PM 70S achieves 115 mg Lys/mL. The exact capacity depends on the product series, pore size, and functional group selected.

Can these microspheres be used for large-molecule protein purification?

Yes. The supermacroporous structure allows large-molecule proteins, antibodies, and protein complexes to access internal binding sites, maintaining structural integrity while achieving high yield and high activity recovery. The hydrophilic surface modification minimizes non-specific adsorption, ensuring clean separations even for sensitive biomolecules.

What functional groups are available?

Four functional group options are available across both platforms: SP (strong cation exchange, -CH₂SO₃⁻), Q (strong anion exchange, -CH₂N⁺(CH₃)₃), CM (weak cation exchange, carboxymethyl), and DEAE (weak anion exchange, diethylaminoethyl). Strong ion exchangers (SP, Q) are recommended for most virus purification applications due to their pH-independent binding characteristics.

What is the maximum flow rate for these chromatography media?

Flow rates range from 150 cm/h for the Poly15 series up to 1,200 cm/h for the Poly 50M/50G/50V PS-DVB series. The PMMA series operates at 150–750 cm/h. The fast mass transfer kinetics of supermacroporous microspheres enable efficient separation even at these elevated flow rates, significantly improving process throughput.
