Indian scientists have got the biggest breakthrough so far in the science of genome sequencing. For the first time in the world, scientists have developed a technique to detect the mutation of the corona virus in just one hour through paper, which is named Feluda Ray (RAY). Last year, a test kit was prepared under the name Feluda, which is currently being used in many states.
Scientists from the IGIB Institute of the Council of Scientific and Industrial Research (CSIR) in New Delhi developed this rapid variant detection assay (ray) technology between January and May this year. Generally, genome sequencing of a sample takes a long time and cost. For this, high-end labs are also needed, which is very lacking in India. At present, sequencing is going on in 10 labs. Whereas recently 17 other labs have started. There is no sequestration facility at the district level. The situation is that till now more than 37 crore samples have been tested in the country but out of these only 30 thousand samples have been sequenced. This situation is when in the second wave so far many serious variants including Delta are in front of the country.
Completed studies
Dr. Aijiaibi according Sodyarthy devajyoti Chakraborty. Souvik friendship and Dr. dr.. Rajesh Pandey monitoring Manoj Kumar, Sneha Gulati and so began studying to learn a simple process Sikvesing together now been completed . There is a technology called FNCS9 for sequencing which we have used in Feluda Ray. Through this, we completed the readout through paper strips after detecting and detecting SNVs from RNA. This process took about an hour after which we came to know about serious mutations including delta. This technology is by far the easiest and simplest which can bring a big change in the country regarding genome sequencing.
Heavy epidemic on scientists during study
During the study, the second wave of corona epidemic in the country also caught the scientists. During this, if someone got infected, then someone lost his mother or father. The study continued even after this crisis and completed the study with an emphasis on night-to-day sequencing. Devjyoti said that work is going on to identify more and more SNVs through this technique. It will be a big advantage that we will get to know more and more about viruses and their effects.
Now what next?
Scientists say that how to use this technology in India? It is not planned yet but it can be worked out soon as the idea is going on with all other institutions including ICAR. There are indications of a big announcement regarding this in the next one to two months.
Named from Satyajit Ray’s film,
this paper-based technique takes only one hour to detect mutations. Being portable, it can be carried far away. Also it is less expensive than normal sequencing. Scientists say the name Feluda was named last year after it was inspired by a detective character in legendary filmmaker Satyajit Ray’s stories because it gives information about the virus in a matter of minutes. Taking this technology forward, Feluda Ray was developed.
Sequencing started in 2008
Actually the history of genome sequencing science in the world is not very old. In 2008, the first female sample was sequenced in the Netherlands. After this it is being used worldwide since 2014. Sequencing has emerged as the biggest weapon in the corona epidemic because through this one can not only identify the virus but can also be careful knowing its effect.
