MEDINA develops different phenotypic and target-based assays, using enzymatic and whole cell approaches, both on-demand and optimized tests.
Custom development from your tube assay to a microtiter plate (96/384) assay for High-Throughput Screening (HTS), hit confirmation, hit-to-lead and Mechanism of Action (MoA) of the lead.
Bacterial & Fungal Assays
- Fungal synergy (Candida, yeast; Aspergillus, fungi)
- Bacterial synergy (Gram positive/negative)
- Panel human pathogens (Wild type/multidrug resistant/nocosomial strains Gram- & Gram+/yeast/fungi)
- Panel yeast pathogens (six Candida spp)
- Tuberculosis panel of surrogate strains (Mycobacterium tuberculosis H37ra /Mycobacterium bovis)
- Biofilms (Wild type/multidrug resistant Acinetobacter baumannii; Salmonella typhimurium; Wild type/multiresistant MRSA...)
- LpxC (Gram negative-A. baumannii, P. aeruginosa, E. coli)
- Reactive oxygen species (ROS): whole cell ( E. coli)
- Oral pathogens: mutans, L. acidophilus, P. gingivalis
- Absorbance
- Fluorescence: fluorescence intensity (FI)

- HPLC-DAD (Agilent 1290 DAD)
Quality control: We perform QC of each screening plate automatically on signal/background ratio and Z´ score calculations, considering the best plate layout for your assay; a statistically optimal number of repeats are performed for the internal positive and negative controls, and/or a dose-response curve of relevant pharmacological standards when available. Genedata Screener® software and in-house applications help us perform the analysis, visualizations, and management of screening data.
