Genotyping and barcoding services
Cultivar ID, genetic traceability, species ID
 

It is possible to differentiate related species or individuals using molecular markers. These are small DNA fragments that vary in length or sequence withing individuals, populations, varieties and species. At BIOAL we develop molecular markers using next generation sequencing. In addition, we offer genotyping and barcoding services using high resolution melting analysis and Sanger sequencing. These services are customized to clients requirements and require a period for development, which could vary depending on their complexity.

Molecular ID by barcoding

It is posible to determine the identity of a given biological sample such as a bacteria, plant or animal using genetic barcodes. This technique consists in the PCR amplification and sequencing of a specific fragment of mitochondrial DNA from the sample to then ID it by comparison with DNA sequences' databases.

This techniques are often used in biodiversity studies, environmental impact assessments, control of fisheries and commerce of endangered species, food fraud, among others.

In the case of fish, land animals and plants, raw or process samples can be analyzed. BIOAL provides technical support and materials for sampling and preservation of specimens up to their submission to our laboratory. For more information click below.

Cotton Textiles Genotyping

We currently test for Gossypium barbadense, Gossypium hirsutum and hybrids using real-time PCR. Future developments include DNA testing for various cultivars such as Tangüis, Pima and native cotton varieties.

Next Generation Sequencing Projects

We develop NGS projects for marker development (for species ID) and for traceability of biological stocks. These projects are customized for application and/or specific challenges.
