Iranian Scientists Make IG_Gene Card for Safe Storage, Transportation of DNA Samples
“Researchers at the Forensic Medicine Research Center have produced innovative cards for the safe collection, storage and transportation of DNA samples,” said Roqayyeh Raha Parvaneh, a genetic expert at the Forensic Medicine Research Center.
“These cards, which are specially designed with a formulation, are able to preserve blood and saliva DNA for at least 15 years at room temperature without the need for a freezer,” she added.
“These cards are produced with two models, mini card and classic, each of which is used depending on the needs of users in collecting and storing DNA samples,” Raha Parvaneh said.
In a relevant development in July, Iranian researchers at a knowledge-based company succeeded in making a kit which extracts DNA from saliva and enjoys a stabilizer solution to prolong the saliva’s stability for high-quality DNA.
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.
