Bioactivity testing
Whole blood bioassays enable rapid, multi-donor efficacy testing.
These assays are well suited to anticipating serum interferences, storage, freeze-thaw, and batch effects.
Our expert teams design immunology studies by aligning research objectives with the most appropriate models and validated analytics. Predefined assay panels are available for rapid screening, and we routinely add value by building bespoke studies around the needs of our clients to ensure timely, interpretable, and relevant data.
Selection of the correct endpoints and means of quantification is central to success, and our immunology toolbox covers a range of carefully selected and thoroughly validated platforms applied across immune models. This can be applied to answer questions such as:
How does a compound modulate a specific immune pathway?
Use surrogate immune cell lines and blood‑derived immunocyte screens for throughput. Stimulate defined immune pathways and quantify focused cytokine outputs (e.g. IFN‑γ) by RT‑qPCR and HTRF, retaining supernatants for optional downstream or retrospective analyses.
Is there a risk of excessive immune activation or cytokine storm?
Start with ex vivo human whole blood to preserve physiology. Expose donor‑matched samples under standardized stimulation and measure cytokine release kinetics (e.g. TNF‑α, IL‑6), supported by monocyte activation markers to contextualise immune risk.
Does the molecule trigger unwanted adaptive immune responses?
Use primary T‑ and B‑cell systems or bulk PBMCs with antigen‑specific stimuli to evaluate immunogenicity potential. Assess T‑cell activation and recall responses using flow cytometry with intracellular cytokine staining, complemented by immunoglobulin release profiling.
How does immune modulation translate in a disease‑specific context?
Select immune models aligned to disease biology, such as tissue‑resident immune systems, ex vivo culture models, or immune tumour co‑cultures. Measure context‑specific responses such as target cell apoptosis in tumour co‑cultures, or cell infiltration in inflammatory disease models, using targeted molecular and spatial immune profiling.
Our analytical platforms are selectively applied across experimental strategies to ensure data continuity and clarity, from our in vitro screens to ex vivo samples, advanced culture models, and in vivo systems.
Core platforms include:
Additional specialised platforms (application‑specific):
Analytical platforms are selected based on the biological system, and research objective. Contact our team for detailed assay descriptions and use cases, validation status, and panel availabilities.
The transition between preclinical and clinical phases is a difficult one, and data continuity can be a major success factor. For assets entering clinical development, QIMA Life Sciences Brazil fully supports clinical trials, alongside integrated analytical chemistry, formulation development, and regulatory support.
QIMA Life Sciences also acts as a provider of European dermatology clinical trials, and can supplement any trial with cutting edge clinical imaging, and non-invasive clinical sampling and bioanalysis support services. Our teams regularly continue to support clients during clinical phases across multiple indications by performing ex vivo analyses of clinical samples. Through these services, we endeavour to maintain continuity of immune profiling, biomarker assessment, and data integration across treatment development.

How do you determine the right immune model for a programme?
Our scientists directly collaborate and engage with the programme. Model selection is guided by the biological question, the exact needs of the programme, and the intended use of the data. Early-stage programs with a clear mechanistic hypothesis often start in targeted cell line systems or primary cell assays for throughput and control. As hypotheses evolve, more physiologically relevant systems – whole blood, ex vivo tissue models, or in vivo studies – are introduced to validate findings in context and produce the data that’s needed for regulatory submissions and go/no-go milestones.
How do you choose between readouts and the platforms to measure them?
The choice depends on many factors. For example, when deciding what cytokines to analyse in an assay and whether to use single or multiplex readouts, we factor the pathway and mechanism under investigation, total number of analytes required, the sample volume, and the resolution needed at the stage of the pipeline.
Multiplex cytokine analysis is efficient when broad immune signatures are needed from a single sample, or research is highly exploratory. Single-plex ELISA or HTRF is often suggested when a specific analyte needs to be quantified with high sensitivity, when cross-reactivity between assays is a concern, or to hone the focus and statistical power of an assay. The exact selection of model, stimulus, and readout is often under-estimated in immunology programmes and this is something our teams recognise and provide expert guidance on.
What is an ex vivo whole blood bioassay, and when is it preferable to isolated cell models?
An ex vivo whole blood bioassay exposes freshly collected blood to a test compound or stimulus while preserving native immune cell populations, cell–cell interactions, plasma proteins, and autologous soluble factors. This contrasts with assays using isolated PBMCs or individual immune cell types, where the physiological environment is disrupted. Whole blood is generally preferred when the research question involves systemic immune activation, when plasma-dependent immune mechanisms are relevant, or when early immune safety profiling requires a system close to human physiology.
For programmes where cost, speed, throughput, reproducibility, and low manipulation are priorities – particularly biologics and immune safety assessments – whole blood is a powerful starting point. Isolated cell models can offer greater experimental control and are well suited to mechanistic dissection of specific immune pathways, but we routinely use both as complementary platforms to progress a candidate.
Can whole blood be sourced from non-human species for cross-species studies?
Yes. Whole blood bioassays can be performed using blood from multiple species, including rodents and canines, supporting cross-species reactivity, veterinary research, and comparative pharmacology studies. Species-matched whole blood formats are used where understanding the immune response in the intended preclinical model is relevant to study design — for example, when confirming that a compound active in human whole blood produces a comparable response in the species to be used for in vivo studies.
Of course, species specific blood samples are also used to test the safety and efficacy of veterinary therapeutics.
Can primary immune cell studies be integrated with ex vivo tissue models and in vivo studies in a single programme?
Yes. Multi-component programmes that span primary cell assays, ex vivo tissue models, and in vivo inflammation studies are a core part of how QIMA Life Sciences collaborates with clients. Circulating immune cell data from PBMC or whole blood studies can be compared to responses in tissue-resident immune populations – for example.
This integration is not automatic: study designs need to be planned with cross-system comparability in mind. Our scientific team can design for data continuity across model systems, which is why early-stage feasibility discussions are valuable – they shape how data will connect across the programme, and also help introduce our ethos of scientific collaboration, adaptation and continuity.
I don’t see the disease or immune pathway I’m interested in listed on this page. Can you still support my research?
The diseases and immune pathways presented on this page are illustrative examples, rather than a complete list of the immunology and inflammation research supported by QIMA Life Sciences.
Our immunology teams regularly work with Pharma and Biotech partners on additional or emerging disease areas and immune mechanisms not explicitly shown here. Support is determined based on factors such as biological relevance, model suitability, translational feasibility, and development stage. Where appropriate, we can select, adapt, or design in vitro, ex vivo, and in vivo immunology studies tailored to the specific research objective.
If your disease area, target, or immune pathway is not listed, we encourage you to contact our immunology team to discuss your program. Following review, we can confirm how your research can be supported within our immuno‑inflammation platform, and advise on experimental approaches.
Immune and inflammatory pathways sit at the core of many therapeutic areas, from allergy to chronic diseases to immuno‑oncology. QIMA Life Sciences provides a connected portfolio of advanced in vitro immunology models, disease‑specific in vivo systems, and validated analytical platforms to help translate immune biology into actionable decisions.
Our integrated approach supports immune profiling, mechanism‑of‑action studies, safety assessment, and translational validation across discovery, preclinical, and clinical phases. Whether you are at the hypothesis stage or deep into a preclinical programme, our experts will work with you to identify the right models, design the right study, and interpret what the data means for your next decision.
