We are glad to announce that we were granted a patent for the "Method of unmarked single-molecule DNA sequencing and the device for its implementation" in USA!

In the patent the way and the device of determination of the nucleotide sequence of a molecule of nucleinic acid is offered.

Demonstration of a program that is designed to recover the nucleotide sequence using modelling data

At present, the debugging of the layout of the key nodes of the DNA sequencer necessary for conducting experiments on sequencing of custom oligonucleotide is being completed, the results of which will be formed and demonstrated by the program that we have developed for this task Today we provide
opportunity for site visitors to get acquainted with the work of this program using the example of synthesized data that emulates the sequencing data of a custom oligonucleotide using the layout of the key nodes of the DNA sequencer.

The program implements the original diffuse nucleic acid sequencing algorithm, which works with four source data files. The data for these files are generated by digitizing the sensor signal, which registers the facts of charge separation as a result of embedding (immobilized on the sensor surface) polymerase of each nucleotide during the polymerization reaction of a looped single-stranded oligonucleotide alternately in four different working solutions, respectively. Working solutions of nucleoside triphosphates are alternately fed to the sensor surface, each of the solutions having one type of nucleoside triphosphates, the molecules of which are concentrated to limit the rate of synthesis of the custom oligonucleotide. According to the sequencing algorithm, on average, the time intervals are longer before embedding the nucleotides of a species whose concentration was reduced against the normal concentration of the nucleotides of three other species in the working solution. Since, at the sample preparation stage, the name of the nucleotide species is known, its concentration is reduced for each working solution, the software tools for the key design of the DNA sequencer key nodes form time sequences for the sensor to record oligonucleotide synthesis results for each working solution in the form of a sequence of discrete time intervals containing logical units “ 1 "and logical zeros" 0 "; moreover, the logical unit "1" denotes the time interval that corresponds to the embedding of nucleotides, and the logical zero "0" denotes the time intervals when the reaction results were not recorded. The sequences of logical units “1” and logical zeros “0” thus obtained are recorded in four files corresponding to four working solutions. The program sequentially processes the data in four files, using the original algorithm sets the threshold value of the time interval for the time sequence of each file; with the threshold value all time intervals are compared between logical units “1” on the time sequence and sorted into long and short. Long time intervals correspond to the incorporation of known nucleotides, nucleotides of the species, the concentration of which has been lowered in the working solution

You can get acquainted with the work of the program by watching the video, which we specially recorded for this.

The program demonstrates the assembly of the nucleotide sequence of a custom oligonucleotide on model data; the data for the same Program, but obtained by digitizing the signals generated by the sensor as a result of recording the separation of charge pairs during the polymerization reaction of a custom oligonucleotide on the layout of the key nodes of the DNA sequencer, will be provided in the near future, and will also be used by the program for assembly and demonstration The nucleotide sequence of the custom oligonucleotide.

Charles Edward Shearer, General Partner, G&S I Fund LP (USA):

We have long been interested in the breakthrough venture projects in the field of medicine with a rich technological basis and high potential for commercial success. We were happy to make a positive decision about investing in the high-tech project, presented by GAMMA-DNA LLC. Our decision was based on the results of the deep due diligence, as well as the communication with the project team. We assessed the risks as acceptable for us at the pre-seed stage both due to the technological perspective of the project and its feasibility and due to the experience and professionalism of the project team: each of the technological directions and the direction of the business development are headed by experts with the deep knowledge and practical experience in their professional fields.

The uniqueness of the technology and its strategic potential to competitors are impressive. We intend to assist GAMMA-DNA LLC in building commercial and partnership relations and entering the markets of Asia and the USA, including licensing and promotion.

Nadya V. Matveyeva, Head of Business Development and Investor Relations, GAMMA-DNA LLC:

G&S I Fund LP is an important strategic partner for us – both in assisting in entering foreign markets and in the attraction of foreign investment for the subsequent rounds. The US market is monopolized by the leader (Illumina) and initially was not in the list of our strategical potential foreign markets. But with the assistance of the G&S I Fund LP team, the issue of representation in the US may well be considered.

Our key task today is to ensure for all the shareholders of the company the optimal balance between the volume of new investments attracted and the speed of R&D and business development in order to reduce the time to market.

Also, in October we’ve developed technological regulations for the manufacturing of two types of sensors and we’ve developed the analog-to-digital circuit and signal processing topology for charge-sensitive matrix cell in accordance to TSMC technology in October.

Polymerase development: we’ve started - in partnership with ZETHEA


On 20.07.2018, our new partner – ZETHEA INC. (USA, Silicon Valley) – has started to develop a specially modified polymerase. Polymerase is an enzyme necessary for carrying out the polymerization reaction –an important part in the process of sequencing (decoding) the DNA molecule. The quality of modification affects the result of sequencing, its timing and (in conjunction with our sensors described in the news 13.07.2018) the accuracy of the result.

Polymerase is developed in ZETHEA laboratory according to our Work Specification. In the coming year, we get three batches of enzyme for testing. A sample will be selected that works most efficiently in the process of demonstration of sequence of the ordered oligonucleotide.

In the next stage (in a year), the efficiency of the experimental and prototype polymerase will be checked by the achievement of the planned rate of the polymerization reaction, including on the TSMC matrices of the sensor cells (see news from 13.07.2018) – this rate will allow sequencing of full genome for 4 hours, with an accuracy 99,9999%.

We will also obtain methods for the production of the selected enzyme with the best efficiency. Thus, we will be able to manufacture polymerase in our laboratory in the quantities required for testing, or go on with production partnership with ZETHEA.

Two major contracts were finally approved and signed at the beginning of this week. These contracts contribute to the project technological goals achievement for this year and form the basis for the Sequencer industrial sample development.

Our new partners – MSU and NAUTECH LLC – will carry out works and consultations in accordance with Works Specification by GAMMA-DNA:
1)    Manufacturing of two types of nanoscale transistors (sensors) for polymerase immobilization (MSU),
2)    Adaptation of transistors for industrial technologies (NAUTECH LLC).

Our team will choose from two types of transistors the best one with the highest sensitivity to the results of immobilized polymerase work as well as compliance with the TSMC, industrial technologies, where we are planning to manufacture shuttles for future production of ultra-cheap sequencer matrices of GAMMA-DNA LLC. Thus, we initially minimize the design time of sensor cell matrix chips and hedge the technological risks of industrial launch.

At this stage (in 353 days), the sequence of the ordered oligonucleotide (DNA fragment) will be demonstrated on the selected sensor installed on the layout of the DNA sequencer key nodes.
