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 (UTEX Price Guide). 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. Additional services are detailed in the Biochemical Analysis page.
