TruCulture

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.

TruCulture Procedure

TruCulture tubes are pre-loaded with cell culture media and immune stimulant(s) or drug candidates. Blood is drawn directly into the TruCulture tube and incubated in a dry heat block. Supernatants are collected by simply inserting a valve separator to separate cells from the culture supernatant.

TruCulture Procedure, Collect

01. COLLECT

Draw 1 mL of blood directly into the TruCulture Tube and break off the plunger.

TruCulture Procedure, MIX

02. MIX

Gently invert tube to mix 3 to 5 times

TruCulture Procedure, Incubate

03. INCUBATE

Place tube in 37ºC heat block for up to 24 or 48 hours.

TruCulture Procedure, separate

04. SEPARATE

Manually insert valve to separate supernatant from the cells. Collect supernatant and cell layer for downstream analysis.

Applications

TruCulture Applications

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.

Advantages

Advantages of TruCulture

  • 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.
  • Only inexpensive heat block needed, no lab equipment nor centrifugation steps.
  • Has been successfully deployed in hundreds of clinical drug trials.

Disadvantages of Traditional PBMC

  • 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.

Traditional pharmacodynamic whole blood experiments are generally short in duration (2-6 hrs) as a consequence of poor culture conditions leading to premature termination of the normal physiological immune response. A longer more robust response usually provides higher sensitivity and greater relevance than short incubation times that may only lead to the release of stored pre-synthesized mediators.

Analysis

Myriad RBM provides quantitative measurement of immune related proteins from TruCulture supernatants. Whether your specific application requires a broad range or a focused set of analytes, Myriad RBM’s panels are designed to meet your needs.

TruCulture® OptiMAP is an immunoassay testing panel validated and optimized to quantify the effect of TruCulture stimulations.  It is a cost-effective test comprised of 13 biomarkers that captures the diversity of responses to microbial, viral, and T cell stimulants.

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.
