Iranian Scientists Make DNA Extraction Kit from Saliva
Abolfazl Motahhari, the managing director of the knowledge-based company, said that the most common way of DNA extraction is by using blood cells, adding, “This method is difficult for elderly patients, pregnant mothers, infants and young children, and sometimes it happens with difficulty and it is more difficult for the patients whose blood clots quickly or those who have anemia.”
He described extraction of the DNA from oral saliva as an alternative method for this problem, noting, “Since the mouth is full of bacteria, the extracted oral saliva is contaminated, and the amount of bacteria present should be reduced during a certain process and by washing, and then by using a stabilization kit, saliva can be kept stable at room temperature for a certain period of time so that laboratories can have high-quality DNA.”
Motahhari also referred to another product of the company, saying that it is an insulated chamber incubator that is used in biological laboratories for the cultivation and growth of living samples like cells, microbes, incubating eggs and spermatozoa.
He added that the PLT01 device is another product of his company which has a heating system by using fluid heat transfer and is applied for melting and heating the liquids in laboratory bags or bottles that are intended for medical transfer or injection in living tissues, and these fluids are usually whole blood, blood products, plasma and other injection solutions.
In a relevant development last September, scientists at an Iranian company had applied nanotechnology to make different types of DNA and RNA extraction kits.
"Our DNA and RNA extraction kits are 70% cheaper compared to the foreign samples and they can perform extraction at a high speed. We have no dependency on foreign countries for production of these kits,” said Amir Shiralizadeh Dezfouli, the managing director of Ronash Technology Pars company.
“By using these magnetic nano kits, the process of making a test to presenting the results has reduced to less than three hours. This technology can be used to isolate various nucleic acids of pathogenic viruses like AIDS and influenza,” he added.
The company also makes various types of products like nanomaterials, gold nanoparticles and magnetic nanotubes which have received four nanoscale certificates so far.
