Extend your research by partnering with
MTTlab - an expert in testing services for the
biomedical, biotechnological,
pharmaceutical and food & beverage
industries.
MTTlab offers testing services in the biomedical,
biotechnological, pharmaceutical and food & beverage fields,
as well as providing assistance with early to mid-stage drug
development both in-vitro and in-vivo. MTTlab assists clients
in fulfilling their needs and requirements in the Research &
Development field of Cellular and Molecular Biology,
Biochemistry and Pharmacology.
MTTlab services are available worldwide to private
companies, academic institutions and government research
centers.
MTTlab’s competitive flat rate price structure allows
compound in vivo testing already during the research phase.
MTTlab can follow up promising compounds from these early
tests during the preclinical development program.
Relying on the network of companies we have created,
MTTlab offers complete one stop preclinical drug
development packages creating best value for highest return
of investment.
Services Available
In vivo Studies (toxicology, efficacy, behavioural, disease
models) on mice.
Preclinical in vivo evaluation of the anti-tumor activity of
a test compound.
In vitro testing (Cytotoxicity)
Molecular Biology, Biomarker Assay
Medical Device Testing (both in vivo and in vitro)
Testing and Certification of Food & Beverages and Functional Food products
In Vitro Studies
MTTlab provides clients with reproducible and consistent in
vitro assay platforms, expertise in standard or custom assay
design and implementation, approximately 40 cell lines
available in-house (custom cell lines may be provided by the
client). The most requested assay platforms include Cell
proliferation and cytotoxicity (IC50/IC90 determination) using
Sulforhodamin B (total protein assay), Resazurin
(fluorescence cell metabolic assay) or MMT (cell metabolic
assay). Cell culture assay gives a rapid and lower cost
evaluation of drug activity in a range of tumors, as well as
minimizing the risk of failure of in vivo assays.
Cell viability assay (IC50, IC90 testing):
Cells: most standard cell lines are available. If the sponsor
requires a specific cell line not available in house, MTTlab can
either purchase it on behalf of the sponsor (direct costs only)
or the cell line can be provided directly by the sponsor (with
negative Cell Contamination Test). A growth curve is
established first for new cell lines.
Assay: Cell viability assay is offered with the option of various
readouts such as SRB (NCI standard test), Resazurin, MTT or
in situ Western Blot (with additional charge for antibody and
Ab testing). The default format (subject to customization) is
96-well plate format, up to 5 compounds, nine two-fold
dilution steps and eightfold testing of each concentration.
Standard readout statistics are provided.
In Vivo Studies
MTTlab specializes in carrying out and evaluating preclinical
tests of novel oncological compounds and medical devices.
MTTlab offers small/medium size (up to 500 mice in a single
experiment) in vivo studies (toxicology, efficacy, behavioural,
disease models, biodistribution) and relevant in vitro studies.
In vivo oncology testing
MTTlab offers following experimental models:
Xenografts Allografts Metastasis, Leukemia and Lymphoma, Orthotopic Experiments upon request (not included in
the flat rate package) Toxicology Testing DRF in mice.
Please enquire for more extended toxicology studies
Various in vivo tumor models are available. All in vivo tumor experiments use tumor fragment-based technology or in vivo propagated (i.p.) tumors. Each animal is identified via micro-chip and randomization into experimental groups is performed according to the highest standards.
In standard experiments, 7 to 12 mice are used per test group and each experiment includes a vehicle and selected chemotherapeutic control groups. As per sponsor request, smaller groups and/or more diverse compounds can be tested in a single Study. MTTlab calculates the study cost according to the number of mice and no setup fee is added.
“Ready-to-Use” tumor models are shown in the table below; lead time can be as short as 4 weeks from order to first treatment. Please inquire for other models.

Ex vivo oncology testing
MTTlab provides clients with a comprehensive package of ex
vivo tests. Tumor bearing mice are treated with anti-tumor
drug. The tumors are isolated and specific tests are designed
by the client or MTTlab for mode-of-action studies in tumor
tissue. These tests can also serve as the basis for biomarker
studies and to stratify patient populations for subpopulations
most likely to respond to therapy. Client tailored experiments
can be designed employing in vivo tumors in mice either
from cell culture or primary tumor sources.
Various in vivo tumor models are available, and all in vivo
tumor experiments are performed using:
tumor fragment based technology or in vivo propagated
(i.p.) tumors;
animals marked with micro-chips;
meticulous randomization into experimental groups
according to the highest standards;
General workflow of an ex vivo experiment:
1. Tumors in mice are induced by using either cell culture
or primary tumor source.
2. Tumor bearing mice are treated with anti-neoplastic
agents.
3. Tumors are isolated and processed according to the
client's request (see below).
4. Specific tests designed by either MTTlab or the client are
used to analyze tumor tissue.
5. Tests are designed to establish anti- neoplastic agent
mode-of-action, a basis for biomarker studies or to
identify patient subpopulations most likely to respond
to therapy.
Post-treatment tumor can be processed (and delivered) as:
Frozen tumor
Paraffin embedded tumor
Tumor extract (ready for WB, total extract, enriched
fractions for nucleus, cytoplasm, chromatographic
fractions)
RNA/DNA prepared for sequencing, microarray and PCR
Food & Beverage, Nutraceutical Certification
MTTlab is also active in the field of testing and certifying food
products, beverages and functional food (Nutraceuticals)
products.
