Explore Genetech’s DNA Typing Services for legal paternity, crime scene analysis, and identity verification in complex cases. DNA Typing Services Child custody and maintenance: In cases where one parent is claiming the custody and maintenance of a child and the other parent is refusing to accept parentage. Proof of adultery: Especially in divorce cases where the paternity of the child is suspect, and the wife is being accused of adultery, DNA typing can be used to determine whether the husband is the father of the child. Rape, which has resulted in pregnancy: DNA typing of tissue samples from the mother, child and suspected offender can be analysed to determine whether he is the father of the child. Testamentary cases: When a deceased person's wealth is to be distributed among his or her heirs, it is sometimes necessary to determine who the heirs are. DNA typing can be used to prove blood relationship to the deceased individual. Immigration: Individuals and families interested in establishing a proven biological link to their relatives ultimately enhance their chances of a successful application for immigration. Identity testing in cases involving immigration may include answering questions of paternity, maternity, and sibling relationships. Twin studies: DNA typing can be used to determine whether twins are identical or not. Identification of mutilated bodies: When a deceased person's body is mutilated and cannot be identified directly, such as in fire, vehicle accidents, bomb blasts, or due to prolonged burial, it is possible to identify these persons by comparing their DNA profiles with that of their close relatives'. Murder, violent assault, robbery: In these cases, a sample of tissue from the criminal is sometimes found at the scene of the crime, and if there is a suspect, DNA typing can very accurately determine whether the sample of tissue belongs to the suspect, thereby linking the suspect to the crime. Furthermore, a sample of tissue from the victim may be found on the criminal (such as blood stains on the criminal's clothing). Similarly, DNA typing can be used to determine whether the sample of tissue belongs to the victim in such cases, thereby connecting the suspect to the victim. Rape and other sexual offences: In these cases, semen and saliva samples may be obtained from the body and clothing of the victim. DNA typing can be used to determine whether the sample of tissue belongs to the suspect, thereby linking the suspect to the crime. In such cases, DNA typing can be used very effectively to identify the criminal only if the offense is reported immediately, and DNA samples are taken as soon as possible. Establishment of identity in insurance claims: It is often necessary to establish the identity of a claimant in life insurance claims. DNA typing can determine the relationship of the claimant to the insured individual. DNA typing is also extremely effective in identifying individuals who have died in accidents or by other causes, and whose bodies have been severely mutilated making conventional identification impossible. Hence, DNA typing can be used to confirm the death of the insured person. Establishment of a criminal DNA profile data bank: Many countries have enacted legislation to establish a DNA databank, containing profiles from individuals convicted of specific crimes, especially violent crimes and sexual offences. Law enforcement agencies search these databanks for matches with DNA profiles from biological evidence of unsolved crimes. Using these databanks, law enforcement agencies have been successful in identifying suspects in cases thought to be unsolvable. Such databases are also a powerful deterrent to crime because the criminal knows that his DNA profile is on record.

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

Discover our testing services for genetically modified (GM) foods. Our validated method ensures accurate results, supporting food safety and certification for local farmers, manufacturers, and exporters. 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.
