Profile code: 4200Technology offer
A Russian company from Akademgorodok, Novosibirsk, developed a scanning flow cytometer of a new generation. Due to an original optics system and data processing algorithm, developed by the company, the volume of processed information is significantly increased. The technology allows early diagnostics of oncologic and immunologic diseases by blood cells morphology. The company is interested in a joint venture or a license agreement.
The technology of flowing cytometry is used to diagnose cancer and immunological diseases by morphological parameters of blood cells. This technology appeared in laboratories 40 years ago and has now exhausted the technical potential of the development. This is particularly evident during the haematological analysis, when detailed information on blood cells of a patient with clinical abnormalities is needed. In these cases, diagnostic laboratory staff uses an optical microscope to study the samples, it leads to an increase of the subjective factor in the analysis and, ultimately, reduces the accuracy of the analysis in view of little amount of statistics.
Unlike the standard flowing cytometry, the proposed technology of scanning flowing cytometry (SFC) allows measuring the morphological characteristics of the particles in a wide angular range, which increases the amount of data received. As a result, the blood cells can be characterized by a set of static indices, for example, the size of cell, the size of membrane area, the size of the cell nucleus, the density of nucleus, cell shape, etc. During the kinetic measurements of intra- and intercellular processes, the following dynamic characteristics of studied processes are defined: membrane permeability, cell aggregation efficiency, speed of the antigen-antibody reaction on membranes, the membrane stiffness, etc.
The technology offers piece-by-piece analysis of cells in flow with speed up to 300 cells per second, providing a high statistical accuracy, and it can reliably detect small populations. The cell flow is illuminated by the laser beam, light scattering of each of the moving cells is measured, the measured data are analysed and the conclusion of a cell and its characteristics is performed. A typical cell size for analysis is 0.1-20 microns.
Therefore, scanning flowing cytometry allows decoding of subtle mechanisms of the disease in each patient, monitoring the results of treatment, and timely adjusting it depending on the sensitivity of tumors to therapy.
Personalized selection of therapies, adjustable for type of the disease, increases the success of the treatment of blood cancer diseases, reduces the duration (and therefore cost) of treatment. This eventually leads to a reduction in mortality from cancer, saving of labor force, increase in average life expectancy and improved quality of life.
Innovative aspects
The main difference of scanning flowing cytometer from the flowing cytometer of standard configuration is an optical system in which light scattered from a single particle is scanned over the aperture of the photodetector during its motion in flow. Thus, light scattering is not measured in two of the solid angles, but continuously in the interval of angles, forming a light-scattering indicatrix. In effect, the light scattering indicatrix acts as fingerprints in recognition of the particles, and contains all the necessary information on the morphological characteristics of the particles. To determine the characteristics of a particle with original mathematical methods the inverse scattering problem is solved (which is not a trivial task, even in the case of spherical homogeneous particles). This allows getting a greater amount of information, despite that it requires a smaller amount of consumables than the analogues.
The main advantage of a scientific solution is a significant increase in the measured data of a single cell in the population. Blood analyzer based on scanning flowing cytometry provides an extensive set of parameters that can detect the disease at an early stage, and make an accurate assessment of treatment quality.
The effect is achieved by using a combination of two innovations: the original optical system and the developed algorithm of data processing.
Due to uniqueness of the proposed methods of analysis, the analogues of this diagnostic equipment are not available at the market.
