A Whole Blood Collection and Culture Tube for Standardized Immunophenotyping Procedures

TruCulture tubes are designed to capture immune cell activity at the time and place of sample collection, thereby minimizing the bias and variability introduced by sample shipping and manipulation. These revolutionary tubes consist of an integrated whole-blood collection and leukocyte culture system that is reliable, simple to use and does not require 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.

How TruCulture Works:

TruCulture tubes simplify and optimize the procedure for immune stimulation, assuring standardization and harmonization of results across different laboratories.


TruCulture tubes are pre-loaded with cell culture media and your choice of stimulant. The tubes are sent frozen and shipped directly to the collection site.

1mL of blood is drawn directly into the tube.


The tubes are incubated in dry heat blocks at 37°C for at least 30 minutes and up to 48 hours, depending on the application.

After incubation, an easy to use mechanical separator is inserted to stop the reaction.


The frozen tubes should be sent to Myriad RBM’s testing laboratory for analysis of secreted cytokines and chemokines.

The tubes are also compatible with flow cytometry and gene expression analysis.

TruCulture Tube Components

TruCulture has been utilized as a whole-blood stimulation system by researchers and drug developers in several fields to reliably measure immune response for the following applications.

  • Pharmacodynamics (including dose response)
  • Functional immune cell analysis
  • Disease characterization
  • Patient stratification
  • Genotype – to – Phenotype association studies

In one pertinent example, our partner, The Institut Pasteur, demonstrated the indispensable benefits of TruCulture in The Milieu Intérieur (“Environment Within”) project. Briefly, the Milieu Intérieur project is working to establish the determinants of a healthy immune response by identifying the genetic, epigenetic and environmental factors that contribute to the observed heterogeneity of immune responses. The challenge of the project is to establish the boundaries of a healthy immune response, and to that end, the Milieu Intérieur Project recruited 1,000 healthy individuals stratified across age (five-decades of life from age 20 – 69), and gender (1:1 gender ratio). TruCulture tubes were an integral part of the Milieu Intérieur clinical study, used as a standardized method for monitoring human response to immune stimulation.

To define the boundaries of a healthy immune response, The Milieu Intérieur project combined the use of TruCulture whole blood culture system with the use of stimuli to define the protein signatures induced by (i) medically relevant bacteria, fungi and viruses; (ii) agonists specific for defined host sensors; (iii) clinically employed cytokines; and (iv) activators of T cell immunity.

OptiMAP Design

A total of 106 immune-related biomarkers were tested on TruCulture samples taken from healthy subjects. A careful selection of the key stimulants listed below were used to monitor a wide range of immune response pathways.  From the 106 candidate biomarkers, we selected a subset of 13 assays that were useful in distinguishing responses to individual stimuli while also revealing population variances.

Microbial stimulants: LPS, IL-1β, TNF-α, BCG, HK C. albicans, HK E. coli, HK S. aureus

Viral stimulants: Poly IC, R848, IFN- α/β

T cell stimulants:  SEB, anti-CD3/CD28

Principle component analysis of 25 normal subjects each tested with 12 TruCulture stimuli and responses monitored with either 106 protein biomarkers or an optimized panel of 13 protein biomarkers. Both analyses show a similar ability to segregate responses by the various stimuli, indicating the utility and efficiency of the OptiMAP panel.


For a more comprehensive understanding of functional immune cell activity, TruCulture supernatant can be tested on any of our Human MAP products. The tubes are also compatible with flow cytometry and gene expression analysis.

Multiplex immunoassay analysis of TruCulture supernatants is conducted in our CLIA-certified testing laboratory.
