Picture perfect performance,
every time.



reproducibility of results

See above for standard curves of 4 PBMC vials from 1 unique batch of the CTL-MAT PBMC.



reproducibility of results

See image above for standard curves of PBMC vials from 3 different batches of the CTL MAT PBMC.


Reproducibility across independent experiments

Average results of 7 experiments carried-out at different sites & times using different PBMC batches.


0.5 EU/ml of LPS can produce an IL-6 concentration of up to 10,000 in the CTL-MAT kit picogram/ml


The CTL-MAT kit has a Lower Limit of Detection (LoD) of 0,004 EU/ml – the highest of any MAT kit.


and counting

PBMC supply that's scalable for the masses.

Unlike any other monocyte activation test vendor, our supply sites in Europe and the U.S. benefit from large-scale state-of-the-art manufacturing that can successfully deliver up to 2,000 vials of 4-donor pooled cryopreserved CTL-MAT PBMC per batch.


How the CTL-MAT Monocyte Activation Test kit works

Step 1

Product incubation
Your parenteral product sample or medical device is incubated with the CTL-MAT kit PBMC.

Step 2

PBMC activation
Overnight, the toll-like receptors of the monocytes recognise the presence of pyrogens and activate the signalling pathways that launch the human immune system response. In turn, this activates the release of cytokines.

Step 3

Cytokine detection
The next morning, the CTL-MAT kit's human IL-6 ELISA is used as a readout to detect and quantify the concentration of released cytokines.

Step 4

Data analysis
Using the LPS standard curve, we convert the measured cytokine concentration captured by the CTL-MAT kit's human IL-6 ELISA to the Endotoxin Equivalent Units/ml present in the product.

"We've got your back – supporting you every step of the way, and then some."

Early on we'll share a list of materials and equipment (and vendors) you'll need to get going and then we'll schedule either in-house or online MAT training depending on your team's experience. As well as helping you devise a protocol tailored to your specific product, we'll schedule either bi-weekly or monthly consultations to walk you through feasibility testing, product-specific validation and routine testing. Finally, you can count on us when it comes to the nitty-gritty of data processing and analysis.

We'll deliver results that others simply can't.


Global, experienced, lightning fast.

Want to get started with MAT but don't have the in-house expertise or would prefer to first investigate feasibility before investing?




Head-to-head, we're always picked.

Almost all our biggest partners go through the process of MAT vendor performance comparison. We've always been the kit of choice.
