Today marks the 66th anniversary of the day which the scientific journal Nature published papers by James Watson, Francis Crick, Rosalind Franklin, Maurice Wilkins and colleagues on the structure of DNA. Their discovery of the structure of DNA was one of the most important scientific developments of the 20th century, and has underlined a huge number of new methods and technologies, which shape our modern world.
Polymerase chain reaction (PCR) testing is one such testing method made possible by our contemporary understanding of DNA. In this testing method DNA from a sample is extracted and added to a PCR mixture containing pieces of DNA (primers) which match the DNA which is being testing for. At Biobest we carry out PCR testing on a regular basis to help veterinary professionals accurately diagnose animals in their care. Your can learn more about how it works here.
PCR testing can also be employed for purposes of avian DNA sexing. Biobest are the only commercial lab in the UK to capable of performing this testing in house and do not refer samples out to overseas laboratories.
