Let us introduce you a good example of this application. A group from the National Institute of Child Health and Development demonstrated that deep learning can be combined with glycan profiling data from lectin microarrays to recognize cell differences with ultra-high accuracy.

Recognition of cell types with ultra-high accuracy and non-destructive way

The lectin microarray used was LecChip Ver1.0 of GlycoTechnica. The lectin microarray has 45 kinds of carefully selected natural lectins and has been widely used worldwide as a de facto standard for lectin arrays since its launch in 2007. Deep Learning, as you know, is now used in various fields as one of methods of AI, and in this research, Google’s TensorFlow was used as the backend, and Keras was used as wrapper software. The layer configuration of this deep Leaning had an input layer of 45 (the same number of lectins) and an output layer of 5 (to discriminate five cells), and hidden layer from 1 to 5. There were five types of cells evaluated (Pluripotent stem cell, Mesenchymal stromal cell, Endometrial and ovarian cancer cell, Cervical cancer cell, Endometrial cell), and a total of 1,577 samples were used for the evaluation. The results were astonishing , and showed a high recognition accuracy of 97.4% overall

Glycan Profiler and Glycan Analysis Software

Glycan Profiling using Lectin Microarray: Glycan Profiler

GlycoStation Reader 2300

It is possible to detect weak biomolecular interactions in a non-destructive way by using an evanescent-field fluorescence excitation technology. GlycoStation Reader was originally designed for scanning Lectin microarray and very strong in its glycan profiling analysis, but is able to scan Glycan array as well.
(We deal with GlycoTechnica’s Products)

Current high-end glycan profiler is GlycoStation Reader 2300 (GSR2300). Comparing with the first generation Glycan profiler, GSR1200, the prominent feature of GSR2300 is that two contradictory functions (i.e., high sensitivity and fast scanning) are satisfied simultaneously. It is able to scan whole microarray surface in only 15 seconds with higher sensitivity than GSR1200. Taking into consideration that the common microarray scanners need around 10 minutes for the scanning, GSR2300 would be a world fastest scanner with high sensitivity. Utilizing its low noise detection capability, the linearity in a lower signal range is also greatly improved, and thereby dynamic range in lower signal side is expanded.

Faster is always better. Please have an experience with the world fastest scanner GSR2300. You could scan a lot of microarrays in a short amount of time, and feel the differences among samples on the moment with astonishment. You will be unable to get back to other scanners if you experience such high speed scanning with GSR2300.

The featuring specs of GSR2300 are as follows;

GT lens
  • Evanescent-field fluorescence excitation method: High sensitivity detection of weak biomolecular interactions with a non-destructive way
  • 3 colors with Cy3, Cy5, FITC as a standard: 8 kinds of optical filters can be installed at the maximum
  • Super high sensitivity: Glycan profiling from only 5 cells
  • Low noise: S/N is improved by 60 times at the maximum comparing with GSR1200 (depends on samples)
  • Super high speed scanning (at the maximum sensitivity): less than 15 seconds
  • Size: 440x592x585mm
  • Weight: 67kg

In order to satisfy those specs, the optical system was redesigned completely, and a proprietary lens (named GT lens) with high NA and wider field size is used in GSR2300.


Ultra-high speed, High sensitive Glycan Profiler

GlycoTechnica is pleased to announce the release of GlycoSuperLite (GSL) 2200, the next generation of GlycoLite. The former GlycoLite will be discontinued, and GlycoSuperLite will be the long-awaited basic glycan profiler with greatly improved appearance and performance. This device is perfect for quick analysis, where you want to know the changes in glycan modification with comparative glycan profiling rather than detailed glycan analysis using LC/MS-MS.

GlycoSuperLite, GSL2200

This unit uses a reduction optical system by 5.5 times with high NA, and can instantly capture fluorescent images of lectin microarrays without scanning. Thereby, ultra-high-speed scanning of 10seconds or less is attained. It is no mistake to say that it is the world’s fastest evanescent wave fluorescence-excited glycan profiler. Sensitivity is not sacrificed even in this high-speed scan, and the detection limit sensitivity reaches 2 ng/mL. Due to the adoption of the reduction optical system, the resolution is reduced to some extent, but with a microarray with a pitch of around 500um, spot identification and analysis can be performed without problems. The miniaturization of the device has also progressed, and the weight of the main body is 10 kg, which is less than half the weight of the former GlycoLite.

  • Evanescent-field fluorescence excitation method: High sensitivity detection of weak biomolecular interactions with a non-destructive way
  • Fluorescence: Cy3
  • High sensitivity: LOD=2 ng/mL
  • Super high speed scanning: 10 seconds or less
  • Size: 345x280x350mm
  • Weight: 10.4kg

The list price is to be announced, but low price that does not disappoint you definitely .

GlycoSuperLite will come shortly

Introduction of the operation of GSL: The power switch of the device is on the front panel. When turned on, the power switch lights up in red. Place the LecChip on a special cassette, cover it, and then set it on the stage inside the device. The brightness of the LED light source can be manually controlled with the knob on the front panel. When loading the cassette, the brightness of the light source should be lowered, and before starting the scanning, it has to be set to MAX. The scanning time is super fast, less than 10 seconds, but no sacrifice in sensitivity. Although the resolution is reduced due to the installation of the reduction optical system, the spots can be clearly identified and the signal intensities of the spots can be quantified without any practical problem.

Glycan Analysis Software

Glycan analysis software, GlycoStation ToolsPro, is attached in GSR2300 as a standard. The current version is 3.0 (abbreviated name, ToolsPro Ver3.0).  It is designed as a user friendly software equipped with all of necessary functions in performing glycan profiling analysis. The featuring specs are as follows.

  • New microarray formats are installed in addition to the current standard microarray format 45lectins/7wells (90lectis/3wells and 18lectins/14wells)
  • Generate grids on scanned images (with TIF format) and digitize spot intensities (16bits)
  • Selection of two background modes (Local Background mode and Global Background mode)
  • Expand dynamic range in a higher signal range using a gain integration (data integration) function with two or more fluorescent images taken at different gains (exposure times), and thereby compensating saturated lectin spot intensities
  • Draw binding curves (sample concentration on transverse axis, and net intensity on longitudinal axis),  easy to select the most appropriate sample concentration
  • Draw comparative glycan profiling pictures (Max 10 comparisons)
  • Data normalization (Raw, Max Intensity, Average, Special Lectin)
  • Copy and paste drawings onto other software such Powerpoint through clipboard
  • Export numerical data used for drawings onto Excel
  • Export data sets onto statistical software and deep learning software (SADL/ESY)
  • Edit lectin names, in order to deal with any lectin panels

New Biosensors

Biosensing, Bioimaging Insturuments

Vaccination for the new coronavirus (COVID-19) is gradually progressing in the world. I think it will take some time, but the pandemic will be over with prevailing vaccination in a couple of years. With advent of various SARS-CoV-2 variants, the efficacy of current vaccines would be reduced. However, it does not always mean that the current vaccines do not work at all, and probably a boost vaccine against such variants will come out.

Gene amplification is essential to get enough detection sensitivity, and therefore, RT-PCR continues to exist as the gold standard. However, in order to speed up and simplify genetic testing further, other innovative methods using isothermal gene amplification combined with CRISPRA-Cas12a, -13a have been developed.

From a view point of POCT, however, small and inexpensive tests are required. Various devices are coming out as prototypes, but the protocol tuning is still very important in terms of speeding up testing. As a detection method itself, an electrical detection method would be probably the most flexible. From that point of view, I think that an electrochemical detection method using the Redox reaction would be the most interesting.


Rhizo MicroBiome Sensor

We are planning to develop a novel rhizo microbiome sensor.

Rhizobacteria coexist around the roots of plants, and the diverse and complex population of bacteria is called the rhizo microbiota. This symbiotic relationship between roots and rhizobacteria is often compared to the relationship between animal intestines and gut microbiota.
In addition to the traditional indicators used in soil diagnosis, chemical indicators such as pH and water content, and physical indicators such as soil density, there is an increasing need for sensors that can detect biological indicators.

Recent advances in gene analysis technology have made it possible to analyze the composition of the rhizo microbiota without the need for isolation and culture of rhizobacteria from soil. The interaction between individual bacteria is also being understood, for instance, in the form of helper bacteria that help mycorrhizal bacteria, and rhizobacteria fix nitrogen and solubilize nutrients (phosphorus, potassium, etc.) in the soil. In addition to exhibiting such functions, it secretes antibacterial substances against phytopathogens and phytoholmons into the rhizosphere as metabolites, greatly contributing to soil fertility.

From this point of view, there is a need for a rhizo microbiome sensor that captures an accurate indicator of the health of the rhizosphere of the plant, and it would be the best to find a way to control soil fertility using it.
