Identification performed by UTEX through microscopy and DNA-barcoding techniques.

Some strains have identifying characteristics that allow identification to the level of genus using light microscopy. UTEX can identify algal strains to the level of species by sequencing their rDNA (18s, 5.8s, and/or ITS 2 regions), or at a minimum, determine the most closely related species for which there is sequence data available. The culture does not have to be axenic, but it must be unialgal and free of other eukaryotic organisms (protists and fungi). For best results, we request that the culture predominantly consist of the algal strain in question. 

Strain identification by:

• Microscopy: $75 USD per strain
• DNA Sequencing: $950 USD per strain ($400 USD deposit due prior to sequencing)
