- Market-leading technical and application support
Measuring vaccine potency or biologically active components is critical to the determination of a vaccine’s effective dose. In addition, the stability of the vaccine has a major impact on its usage for immunization programs worldwide. Octet® Bio-Layer Interferometry (BLI) systems deliver comprehensive characterization of vaccines as well as rapid and reproducible determination of protein concentrations for titer and functional activity assays. A single platform delivers high value across a wide range of applications in vaccine discovery, development and manufacturing.
Product Highlights for Downstream Vaccine Research
Clarification and Filtration
Sartoclear Dynamics® Lab kits: Virus and Protein Harvesting in One Step
Sartoclear Dynamics® Lab kits are designed for rapid harvesting 15 mL to 1,000 mL volumes of cell cultures in the lab, enabling clarification and sterile filtration to be performed in one step. Kits combining a vacuum filtration unit, Sartolab® RF with a PES membrane and a filter aid for clarification.
Concentration and Purification of Viruses
Vivapure® Virus Purification and Concentration Kits
Adenovirus and lentivirus purification kits utilize membrane adsorber technology for fast and safe virus purification. High yields with low endotoxin levels are ideal for downstream use in cell-based assays.

Vivaflow®, Vivaspin® and Vivapure® Ultrafilters
Ultrafiltration devices offer perfect solutions for ultrafiltration needs in protein, peptide, nanoparticle and virus purification workflows. From concentration and diafiltration of the target molecule source (such as a cell culture supernatant) to final concentration, desalting or buffer exchange of the purified protein.
Cost-Saving Characterization of Vaccines and Biologics
Label-free Octet® BLI technology is used in downstream processing to determine titer, potency, and stability of biologics and vaccines.
Cubis® III: Connect. Comply. Simplify.
Cubis® III for Vaccine Development
Sample weighing and accurate lab weighing are critical throughout vaccine research and development, especially in pre-clinical phases where reliable results are essential. From buffer preparation to gravimetric monitoring of purification and formulation, operator safety is paramount when working with toxic or potent viral substances. Sartorius Cubis® III high-performance balances enable touch-free operation, minimizing direct contact with hazardous materials while delivering precision and data integrity. Whether concentrating viral vectors or formulating final vaccine candidates, Cubis® III balances ensure safety without compromising accuracy.

Downstream Vaccine Research FAQs
Yes, Sartoclear Dynamics® Lab Kits with filter aid offer fast and effortless solution for clarification of sample volumes of up to 1L, enabling clarification and sterile filtration to be performed in one step.
It can! Sartorius provides a convenient conversion table to choose a MWCO up to 1/3 the diameter of the target virus. For example, high recoveries of Lentivirus - which has a diameter of ~90 nm - are achieved with 300 kDa MWCO Hydrosart® or 100 kDa MWCO PES membranes.
Ultrafiltration can be used for concentration, diafiltration, washing or purification of nanoparticles. In addition, ultrafiltration can be used to separate free- from nanoparticle-bound or encapsulated APIs. This enables a detailed understanding of nanoparticle functionalization, informing correct dosing while minimizing toxic effects.
Sartorius offers a comprehensive range of lab ultrafiltration solutions to meet the research and development needs for nanoparticles which will be used in tomorrow’s nanomedicines. Centrifugal, pressurized and crossflow devices enable processing of 0.1 mL to 5 L samples, offer superior process speeds compared to conventional techniques, and provide high target recoveries.
Use of centrifugal concentrators for buffer exchange or sample concentration requires optimization of the protocol and correct handling of the device in conjunction with a pipette to ensure:
- Determination of the concentrated sample volume for accurate yield measurement
- Retrieve the full volume of sample in a tall concentrator tube while avoiding sample-to-pipette and pipette-to-sample contamination
- Proper rinsing so that the preservatives used to maintain membrane stability do not elute into the sample leading to anomalous peaks in concentrate analysis
Read Effectively Use Picus® Pipettes with Vivaspin® Concentrators Application Note
Many of the assays used in vaccine and virology research are vulnerable to interference and contamination. Ensuring the availability of RNase/DNase and endotoxin-free water is essential for accuracy. In addition, the purity of laboratory water can influence the quality of viral pseudotypes, with demineralized water significantly decreasing transduction capacity compared to ultrapure water.
Arium® water systems offer ultrapure water solutions suitable for sensitive analytical workflows such as those used in virology and vaccine research. Download the Arium Virus Research Application Note
