Genetically Modified and Other Food Testing Definition Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants. What we do We use a PCR method to identify the most common genetic elements that are generally found in GM crops. The test is very sensitive and able to detect 0.1% GM content. In addition to the common genetic elements, on request, we also offer to detect other genetic elements that are assumed to have been integrated into the plants during the GM procedure. Our test can be applied to crops such as corn, soy, canola, and potato as well as processed food items such as tea, desiccated coconut, bakery & confectionery items, breakfast cereals & snacks, food additives, and others. Validation of method The test method has been validated according to the guidelines given by the European Commission Joint Research Centre for food samples and uses positive (European Certified reference materials) and negative control samples in order to assure the best qualitative results. Who we help Our testing facility has been utilised by the Food Control Administration Unit, Ministry of Health, Sri Lanka for the screening of imported seeds and food products as well as local farmers, manufactures and exporters to certify their products are free from GM food materials.

Molecular Diagnostics Did you know? We pioneered the use of molecular diagnostics in Sri Lanka. This field, which was almost unknown to the medical fraternity in Sri Lanka is now widely used in delivering high quality patient management. Molecular diagnostics is now an accepted and even essential part of the health care system since it was introduced to Sri Lanka by us in 2002. How we strengthened our clients' trust In order to standardise our tests and strengthen our clients' trust, We have applied for and obtained ISO 15189 accreditation. Thus, our tests including those related to molecular disease diagnostics are excellent in all aspects. The importance of nucleic acids Infectious diseases are caused by a wide variety of organisms, ranging from multi-cellular parasites and fungi to uni-cellular bacteria to non-cellular viruses. These organisms cover a wide range of phyla, and have extremely diverse ways of infecting human beings. In spite of these differences, they all possess nucleic acids (DNA or RNA molecules), their hereditary material. This DNA or RNA forms the basis of their individuality, and because it is the basis of diversity, it is possible to identify these organisms from their DNA or RNA. What we offer with PCR technology Unlike other diagnostic methods, which rely on microscopy, culture, biochemical characteristics and indirect antibody detection, molecular diagnostics seeks evidence of a disease at the very basic causative level by detecting the nucleic acids based on PCR (Polymerase Chain Reaction) technology. ​ This technology is also used to detect changes or mutations in our DNA, which can cause disease conditions known as genetic disorders. While some of these genetic disorders are passed from generation to generation, some happen spontaneously. Genetech offers DNA-based testing services for a wide variety of such genetic disorders and cancer markers. Contact us View Price List and Sample Collection Guide

Dr. Nandika Perera Head of Forensic DNA Typing and Parentage Testing Dr. Nandika Perera joined Genetech in early 2004 soon after its inception and was part of the pioneering team led by late Dr. Maya Gunasekera, who introduced molecular diagnostics and DNA typing services to Sri Lanka. In subsequent years, he was promoted to the post of Senior Scientist and in 2010, he became the Head of the Parentage Testing Section. Currently, he is also the Head of Forensic DNA typing and has provided more than 2500 DNA typing reports to the Sri Lankan Judiciary. ​ He together with his team has established several in-house molecular diagnostic tests including a test for prenatal diagnosis of thalassemia disease. More recently, he introduced X chromosome STR typing to Sri Lanka to be used in forensic and kinship analysis. The technique offers a significant advantage over the other commonly used DNA typing methods in resolving some specific cases of kinship which cannot be conclusively resolved otherwise. He is also involved in various other molecular biology related research in collaboration with many state and private universities and research institutes in Sri Lanka. His portfolio of works includes many research publications, some in the world’s leading high-impact journals such as Scientific Reports of Nature publishing group and International Journal of Legal Medicine which is testimonial of his illustrative career in the field of molecular genetics. ​ Nandika is an alumnus of both the University of Colombo and Institute of Chemistry, Sri Lanka. He holds two Honours degrees, one in the field of Molecular Biology and Biochemistry (from University of Colombo) and the other in Chemistry (from Institute of Chemistry, Sri Lanka). He obtained his master’s degree in Molecular Life Sciences at the Institute of Biochemistry, Molecular Biology and Biotechnology, University of Colombo and has completed his Ph.D. in the field of Molecular Forensics at the Faculty of Health Sciences, Open University of Sri Lanka. He is the recipient of many academic awards including the Gold Medal for the best academic performance in his Master’s Degree, the award for the best performance in part 1 examination in Graduateship in Chemistry and the W. F. Peiris Memorial Scholarship in Graduateship in Chemistry.

DNA Sequencing Genetech is an authorised agent for a world-leading company of genomic analysis which provides a wide variety of services including DNA sequencing and oligo nucleotide synthesis. This has enabled Genetech to provide the following services to Sri Lanka at an affordable price range. DNA Sequencing services Capillary Electrophoresis Sequencing CES analyses DNA sequences using Big Dye chemistry (Sanger Sequencing) and the ABI 3730xl analyser. CES can be performed either in individual PCR tubes or in 96 well plates for high throughput sequencing. The reaction can be conducted using both universal as well as custom made primers. The method is commonly used to sequence relatively shorter fragments of DNA for a variety of purposes. Sequencing of PCR products and plasmid CES is generally used for sequencing of PCR products and plasmid DNA up to 1,000 bp in length. A special CES service is also available for the ‘difficult sequencing’ such as high GC rich DNA, homopolymers, repetitive sequences and those with strong secondary structures. ​ In addition, we accept the unamplified DNA and unprocessed biological samples for sequencing services. We also undertake to sequence PCR products containing nonspecific bands. Upon request, post sequence analysis (sequence alignments, phylogenetic tree construction, genome annotation etc.) services are also available to help the researchers interpret the results. Sequencing bacterial and fungal colonies 16S r-RNA gene sequencing is a common method used to identify bacterial species. As per the customer requirement, we undertake to sequence different length options up to 1400 bp. For the sequencing of fungal colonies, we provide three options: 18S rRNA gene (> 1,600 bp guaranteed), 26S rRNA gene (> 1,300 bp guaranteed) and ITS region (> 500 bp guaranteed). We also offer post-sequencing analysis services to assist species identification. Next-Generation Sequencing NGS, massively parallel or deep sequencing are related terms that describe a DNA sequencing technology which has been developed for genomic research during recent years. The technology performs parallel sequencing of millions of DNA fragments which are assembled into single genome using bioinformatics analysis. In contrast to the first-generation Sanger sequencing technology, NGS provides a much more efficient tool enabling the sequencing of the entire human genome within a single day. ​ We offer numerous NGS sequencing techniques such as Whole Genome Sequencing, Metagenome Sequencing, Exome Sequencing, Transcriptome Sequencing and Epigenome Sequencing. Different NGS platforms are available to meet the varying requirement of these techniques. Our scientists will help you choose the best NGS option and platforms depending on your requirement. We also offer to assist in the bioinformatics analysis of NGS data. Contact us
