GRIIS Composition

GRIIS Composition<sup>TM</sup>

Genome Analysis And Identification Of Master Strains

GRIIS Composition targets dietary supplement and probiotics products made of single or multiple strains.

Based on 16S rRNA genes, we check the existence and relative abundance of strains in the product and provide a product composition analysis report. The report can be used as evaluation materials for product reliability and quality check.
