Genomtec innovations

Genetic (molecular) diagnostics is the youngest branch of diagnostics mainly related to the development of molecular medicine. In the last several years we have seen a rapid development of this type of diagnostics. This is connected to the development of technologies that allow precise and fast determination of disease causality based on genetic material identification (DNA or RNA) that could belong to the targeted pathogen.

The best-known methods used for molecular diagnostics include real-time PCR (polymerase chain reaction with a real-time monitoring of product amplification), a technique which was developed in the 1980s. Real-Time PCR allows detection and amplification of nucleic acids, as well as monitoring of the reaction progress.

The solutions developed by Genomtec utilize the isothermal amplification method, which is a much newer, faster and more innovative technology than PCR, commonly used by genetic laboratories. One of its sub-types is LAMP (Loop Mediated Isothermal Amplification) technology, which requires constant temperature, thus eliminating need for heating and cooling of the reaction mixture and reducing time required for analysis. Due to the reaction occurring at a single temperature it is also possible to gain other advantages that play a significant role in point of care (POC) diagnostics, such as reduction of device dimensions and purchase cost, as well as decreasing energy consumption of the system. The LAMP method, thanks to its unique properties, works ideally in mobile devices intended for point of care testing, such as consulting rooms, clinics, ambulances, pharmacies, and hospital wards.


Isothermal technology that accelerates diagnostics

The main advantage of using izothermal LAMP technology is its higher precision of pathogen detection and shorter testing time.

LAMP (Loop Mediated Isothermal Amplification) is an isothermal method, which means it occurs at a constant temperature for the amplification of genetic material (RNA, DNA). This process utilizes a special polymerase, an enzyme responsible for the synthesis of new sections of DNA strands. The polymerase utilized in the LAMP method shows DNA strand displacement activity, however, it has no exonuclease activity. This enables simultaneous relaxation of the DNA helix and synthesis of new DNA fragments, which in not possible when using PCR method.

The LAMP innovation also involves designing the primers, i.e. short oligonucleotide fragments, four to six of which are used in this method. They can hybridize from six to eight sites on the analyzed nucleic acid fragment. Such kit also contains loop primers that greatly accelerate the synthesis of newly created strands.

As it utilizes more primers in comparison to Real-Time PCR, this method exhibits extremely high specificity, short amplification time, as well as ability to detect single gene copies, while exhibiting greater tolerance to sample impurities that act as inhibitors. One temperature range for the LAMP reaction significantly reduces the time needed for the entire analytic process, which is unobtainable with of real-time PCR technique.

SNAAT® Genomtec

Ground-breaking technology and a new standard for isothermal diagnostics

Genomtec Team has invented and patented the unique SNAAT® technology, which enables precise pathogen detection even in 15 minutes.

SNAAT® (Streamlined Nucleic Acid Amplification Technology) due to the proper design of the diagnostic system, i.e. combination of the LAMP method with microfluidics and a contactless photonic heating system, makes it possible to conduct isolation, purification, and concentration of genetic material together with amplification and detection of pathogen-specific DNA or RNA fragments in record breaking time – even in 15 minutes, while maintaining effectiveness equal or better to the currently used lab PCR methods. This shows the uniqueness of the SNAAT® technology invented and continuously developed by Genomtec.

The SNAAT® method can be used for multiplexing (simultaneous detection of multiple diagnostic targets) on microfluidic card, which means that a single diagnostic test can at once detect even up to five pathogens. The combination of nucleic acid isolation, purification and concentration stages executed onto the passive microfluidic card (with no embedded electronics nor electric parts) makes it possible for the SNAAT® to significantly reduce the limit of detection for the target nucleic acid and decrease production costs of disposable reaction cards at the same time. Excellent diagnostic parameters, including sensitivity, specificity and repeatability obtained when using SNAAT® result from the amplification process resistance to the inhibitors that can often be found in biological samples, such as blood, drugs, etc. This makes SNAAT® a unique technology designed for Point Of Care Testing (POCT).

PCR (Polymerase Chain Reaction) is the most often used method in genetic diagnostics. It is one of the genetic amplification (multiplication) methods using the enzymatic process in various temperature ranges. The reaction is initiated by a pair of short nucleotides complementary to DNA strand, so-called primers that guide the enzyme to a suitable amplification initiation site. This method makes it possible to analyze genetic material of low initial concentration. One of the PCR variants is the real-time PCR, where dyes or probes (fluorescently labelled nucleotides) are introduced to the reaction environment and then bind to the target nucleic acid fragment during the analysis.

The SNAAT® method is groundbreaking, as it allows integration of the complete diagnostic process into one platform, thus automating the expensive and time-consuming analytic step of the process that occurs in the diagnostic laboratory by using contactless photonic heating and microfluidics.

The proprietary SNAAT® method allows:

  • ensuring the optimum reaction temperature,
  • stabilizing the temperature output and controling fluid flow in the microfluidic system, and
  • analyzing the amplification results (fluoroscence measurement).

These processes are contactless, using photonic energy, thus revolutionizing the current standard for heating and cooling of the reaction mixture in the PCR test tube, i.e. by placing it in a thermally conductive element, so called thermoblock.

Combining contactless heating that utilizes photon energy with microfluidics makes it possible to miniaturize the system and eliminate the energy-consuming heating system based on a physical energy conduction via thermoblock. As a result we gain a mobile and automated diagnostic process.
