Samudi Mohotti Senior Scientist Samudi Mohotti commenced her professional career at Genetech as a Scientific Officer at the division of parentage testing in 2004. In subsequent years, she was promoted to the post of Senior Scientist and currently oversees the entire process of parentage testing. She is one of the most experienced scientists in the field of DNA typing and has contributed to submit over 3,000 DNA test reports for civil and criminal cases to the Sri Lankan Judiciary. She took part in the development of an allele frequency databases of autosomal STR markers for Sri Lankans ethnicities and co-authored a journal paper in a high-impact journal, Forensic Science International: Genetics. In addition to DNA typing, she is involved in many research projects conducted by Genetech on contract basis to meet the requests from both state and private institutes. She is also a key member of the team which maintains the ISO 15189 quality management system of our laboratory. Samudi obtained her BSc degree in Biological Sciences from the University of Colombo, Sri Lanka and her Master’s degree in Applied Microbiology from the University of Kelaniya, Sri Lanka.

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

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
