The University of Guyana marked a milestone in national scientific development with the launch of its DNA Barcoding Laboratory at it's Turkeyen Campus. This facility, established alongside a new Molecular Diagnostics Laboratory, provides Guyana's first local capability for comprehensive genetic analysis of its rich biodiversity.
"We now have the ability to collect samples and sequence in-country. This allows for the identification of species in-country," explains Dr. Gyanpriya Maharaj, Director of the Centre for the Study of Biological Diversity at The University of Guyana.
"Before this lab opened, all samples collected in-country had to be exported for further analyses. After these analyses, the country would then be informed of new species by the institutions or through publications. Therefore, Guyanese researchers were mostly not involved in the process of genetic or genomic level work."
Prof. Paloma Mohamed Martin, Vice Chancellor of the University of Guyana, adds, "While we had the technical expertise, the impact of not being able to trace, track, and identify species in-country was deeply concerning." The new laboratory addresses this longstanding gap in the country's research infrastructure.
What is DNA Barcoding?
Understanding DNA barcoding starts with a simple truth: every living thing carries a unique genetic signature. This signature acts like a product barcode in a supermarket, allowing scientists to precisely identify different species.
When researchers discover what might be a new species in Guyana's rainforests, DNA barcoding provides definitive answers about its identity and relationships to other species.
The process requires sophisticated laboratory equipment and expertise. Scientists extract DNA from a small tissue sample - smaller than a fingernail - and analyze specific sections that are most useful for species identification. These sections contain enough genetic variation to distinguish between even closely related species, while being short enough for quick analysis.

"In the recent Acarai-Corentyne corridor survey, the processing of eDNA samples immediately detected 55 species that were not found by any other method. This includes five species of mammals, 49 species of fish, and a frog species (Pipa aspera), which is a new record for Guyana. Doing this work immediately gives us a more accurate sense of the incredible diversity of the area," explain Dr. Maharaj and the eDNA team lead Sophie Picq.
Developing Valuable Skills For Guyana's Future
Before the new laboratory opened, Guyanese scientists faced significant obstacles in their research. Genetic analysis required sending samples to international laboratories, creating delays of several months and costs of thousands of dollars per sample. This system prevented local researchers from participating in crucial parts of their own research projects.
The situation particularly affected student training. While students could read about genetic analysis techniques in textbooks, they had no way to gain practical experience with these essential modern research tools.
"In a DNA barcoding laboratory, students can develop a variety of valuable skills. They gain hands-on experience with molecular biology techniques such as DNA extraction, PCR amplification, and gel electrophoresis. Students also learn how to sequence DNA and analyze genetic data, honing their computational skills for bioinformatics," says Dr. Maharaj.
The DNA Barcoding Laboratory provides Guyanese scientists complete control over the genetic analysis process. Researchers now extract DNA, amplify specific sections for identification, and analyze results entirely within Guyana. This capability reduces analysis time from months to days and significantly lowers research costs.
Research Applications
The laboratory fundamentally changes how Guyanese scientists conduct biodiversity research. Local researchers now analyze genetic samples within days rather than waiting months for international laboratory results. This rapid analysis proves especially valuable during field research, where quick species identification can guide ongoing exploration and documentation efforts.
The laboratory's impact became immediately apparent during the recent Acarai-Corentyne Corridor survey, where researchers documented over 1,300 species across 1.3 million hectares of diverse ecosystem. For the first time in Guyana's conservation history, scientists processed environmental DNA samples entirely within the country, leading to the identification of 22 species previously unrecorded in Guyana and 23 species potentially new to science.
This breakthrough enables Guyanese scientists to pursue increasingly sophisticated research programs. They can now monitor endangered species through genetic tracking, study evolutionary relationships between different species, and contribute Guyana's unique biodiversity data to global genetic databases. The ability to quickly process samples in-country also allows researchers to respond rapidly to urgent conservation needs.
"Local DNA analysis capabilities can significantly enhance a country's position in international research collaboration by fostering self-reliance and expertise in genetics and genomics, thereby allowing independent Guyanese-led research. Greater local infrastructure and capabilities allow for faster, more efficient research, elevating the country's scientific reputation. Ultimately, it enables Guyana to be more active in shaping global scientific agendas and addressing international challenges," highlights Dr. Maharaj.
Each analysis completed in the new laboratory strengthens Guyana's scientific capabilities. The facility transforms the country from a source of research samples into a centre for analysis and discovery.
Frequently Asked Questions
What is DNA barcoding and why is it important?
DNA barcoding is a technique that identifies species through their unique genetic signatures, similar to how a supermarket scanner reads product barcodes. It allows scientists to precisely identify species and their relationships to other organisms, which is crucial for biodiversity research and conservation. It will also enable more Guyanese-led research.
How does the new laboratory benefit Guyana's research capabilities?
The laboratory enables local processing of genetic samples within days instead of months, reduces research costs, and allows Guyanese scientists to participate fully in their research projects. This local capability particularly benefits field research, where quick species identification can guide ongoing exploration.
What specific discoveries has the laboratory enabled?
During the Acarai-Corentyne Corridor survey, the laboratory's environmental DNA analysis identified 55 previously unrecorded species, including 5 mammal species, 49 fish species, and a new frog species (Pipa aspera) for Guyana. The survey documented over 1,300 species across 1.3 million hectares.
How does the laboratory impact education in Guyana?
The laboratory provides students with hands-on experience in molecular biology techniques, DNA sequencing, and genetic data analysis.
