A wholeblood collection and culture tube for standardized functional immunophenotyping
Our integrated system captures immune cell activity without specialized laboratory equipment. TruCulture enables researchers to reproducibly ascertain information about immune responses to stress or stimulation, including responses to novel therapeutics. The ex vivo TruCulture procedure preserves physiological cellular interactions to more accurately reflect the complexities of the human immune system, bringing added value to immune monitoring in clinical trials.
Traditional pharmacodynamic whole blood experiments are generally short in duration (2-6 hours) due to poor culture conditions and premature termination of the normal physiological immune response. TruCulture provides a longer, more robust response to enable higher sensitivity and great relevance than short incubation times that may only lead to the release of stored pre-synthesized mediators.
Advantages
- Integrated closed sterile instant whole blood collection and culture system
- Standardized to ensure consistent performance across multiple users and clinical sites
- Reliable, easy to use, and reproducible – eliminates the need for cell manipulation
- Retains all blood components, granulocytes, platelets, red blood cells, soluble factors and Fc receptor expressing cells
- Utilizes an inexpensive heat block, replacing the need for additional lab equipment or centrifugation steps
- Successfully deployed in hundreds of clinical drug trials
Challenges of PBMCs
- Requires separate blood collection and specialized cell culture procedures
- Extensive manipulation, processing, and often freezing/shipping prior to culturing
- Requires technical expertise with increased variability across users and clinical sites
- Requires CO2 incubator, biosafety cabinet, centrifuge, media and cell culture plastics
- Culture procedures/conditions are difficult to standardize for clinical trial applications.
- Open, less sterile, artificial system
- Poor reproducibility

Stimulants
Stimulants for TruCulture tubes
TruCulture tubes are available with a variety of validated stimulants. Estimated lead time for TruCulture tube delivery is 6-8 weeks from receipt of PO, signed contract where applicable, and Shipping Form (2 weeks for LPS and null tubes, which areroutinely kept in stock).
TruCulture tubes can also be customized with soluble substances to target the immune pathway of choice. Contact our Protein Biomarker Center of Excellence to co-develop TruCulture tubes. We can evaluate your stimuli of interest for sterility, solubility, dose response, short and long-term stability, and reproducibility.

Sample Analysis
Analyzing TruCulture samples
Our Protein Biomarker Center of Excellence – which developed the TruCulture system – provides quantitative measurements of immune-related proteins from TruCulture supernatants. We can test your TruCulture samples using our internally developed Luminex- and Simoa-based assays.
TruCulture tubes can also be tested on additional platforms, including the Alamar ARGO HT and Meso Scale Discovery (MSD). TruCulture samples have also demonstrated utility when tested by flow cytometry and gene expression analysis.
