Providing Next Generation Sequencing and Bioinformatics Services
Go to Sequencing


We have already sequenced more than 100 different species (not counting metagenomic projects), over 1000 samples/month processed and we add about one new project every day.

Go to Library preparation

Library preparation

A key element of NGS is the high-quality library preparation. The protocols and equipment used by our team can accommodate a range of needs.

Go to Bioinformatics Analysis and Processing

Bioinformatics Analysis and Processing

Our quantitative and computational analytical unit sits at the cutting edge of bioinformatics research — we use the latest tools and develop improvements to correct short comings with these tools.

Who We Are

Established to radically improve genomic research across AgriLife, TAMU, and the Texas A&M University System

Introducing TxGen, the Texas A&M AgriLife Genomics and Bioinformatics Service! At TxGen, our mission is to revolutionize genomic research across AgriLife, COALS, and the Texas A&M University System by providing world-class laboratory and bioinformatics expertise. We're dedicated to accelerating genomic research across Texas and the world, and embodying the Aggie Core Values of Service, Excellence, Leadership, Loyalty, Respect, and Integrity.

Texas A&M AgriLife Director, Genomics and Bioinformatics

Led by Dr. Charles Johnson, our team of genomics, bioinformatics, and molecular scientists is committed to meeting the next generation sequencing (NGS) needs of the TAMU system and broader scientific community. With over 13 years of experience running a gene technologies lab and more than 3000 completed projects, we've grown to be one of the leading agrigenomic sequencing facilities in the world. We're proud to be recognized as a center of excellence by both Illumina and PerkinElmer, and to have the capacity to process over 200,000 samples per year and generate enough data to sequence 43,000 human genomes at a cost well below most commercial and academic facilities. Investments in personnel and equipment have been critical to providing genomics and bioinformatics infrastructure for student training, faculty retention, and successful R&D initiatives in the areas of agriculture, life sciences, human health, and veterinary medicine.

Allow us to serve you and let's accelerate genomic research together!
