Tecna was founded in Trieste, Italy, in 1994, as a small group of biologists with deep experience in the field of immunodiagnostics. In the beginning, the main activity was focused on methods for the detection of drug residues in food. Since the 2000s, the company has been developing a wide range of test kits for mycotoxins and starting exploiting other technologies than traditional ELISA kits, like lateral flow devices and microplate immuno-arrays. The original concept of ELISA was improved time after time, focusing on different market requirements such as easy-of-use, flexibility, cost effectiveness, fastness, automation.
In 2016 Tecna joined an ambitious project in Eurofins and became part of the global provider of screening solutions Eurofins Technologies, together with Abraxis, Ingenasa, Gold Standard Diagnostics, Immunolab, GeneScan, Amar. Eurofins Technologies product portfolio includes the best technologies available for the analysis of natural toxins, drug residues and hormones, allergens and gluten, GMOs, food pathogens, animal species and animal diseases. Whatever you may need in the field of food, feed, water, environmental and animal safety, you can find it in Eurofins Technologies.
In Tecna laboratories, researchers are working on novel projects and products every day. Our contribution to Eurofins Technologies network is our deep knowledge of immunochemistry, our experience, our curiosity, our science orientation, our technologies, our Quality system as well. Besides, a proper understating of market necessities pushes Tecna to improve its products every day, and offering the best technologies for every requirement:
- Lateral flow devices, also known as cards, strips or dipsticks, are field tests based on a kind of immunochromatography. All the reagents are generally inside the device and this makes the test very easy to perform, by anyone and anywhere. Results are obtained in a handful of minutes: these tools could not be very accurate and precise sometimes, but are definitely the right solutions for goods acceptance controls.
- ELISAs are microplate assays based on the highly specific binding of antibodies to a molecular structure of an analyte or a group of molecules that share it. They exist in a number of different formats.
- Classic ELISA kits usually require to run a number of calibrators or control solutions and the samples in two replicates, that means using two wells per standard / sample. They ensure almost sensitive, robust, precise and accurate results and are suitable for high analytical volumes.
- Fast ELISA kits are second generation assays that speed up the results up to a handful of minutes. Double replicate assay layout is usually not mandatory, that means that the analysis is much more affordable.
- Thanks to high stability and performances robustness, it is sometimes possible to avoid to run the calibration curve all the times. Master-curve calibrated assays are the best way to have precise and accurate analysis and save money also when analyzing a few samples per session.
- Automation is demanded in many laboratories for a number of reasons: reproducibility, reliability, standardization. And, of course, getting the analyst free to do something else. Immunoassays can have different formats to be automatically handled by a dedicated instrument, like pre-sealed all-inclusive cartridges. This innovative device ensures a total protection of both reagents from evaporation and contamination and the analyst from solvent or other toxic substances. Besides, the absence of bottles of reagents minimizes the risk of mistake and ensures a full traceability.
- A microarray is a multiplex lab-on-a-chip: it is a two-dimensional array on a solid substrate that allows the simultaneous anlysis of a number of parameters in the same sample. Solid supports like glass slides or silicon thin-film cells are commonly used for a number of applications, but they have a certain limitation in terms of cost and flexibility. Nanoarray formats in 96 well breakable microtitre plates overcome such limitations and lead to a multiplex test capable of conducting large surveys and high throughput but also the simultaneous detection of many contaminants by users already familiar with ELISA methods.
- Immuno-affinity columns (IAC) are based on a specific antibody-analyte binding. These tools are developed in order to enable sample purification and concentration, thanks to their capability of collecting the contaminant of interest and removing the interfering compounds that can generate background noise both in screening or instrumental (chromatographic methods) analysis. The columns contain a gel bed coupled with specific antibody for the analyte of interest. When the sample flows through the column, the antibodies retain only the molecules of interest, draining interfering compounds into the flow through. By means of an apposite elution solution, the analyte can be collected for further analysis.
