KOTAI Biotechnologies, Inc. (KOTAI, Osaka, Japan) is a spinout from Osaka University's world leading research center, Immunology Frontier Research Center launched in 2016. Our unique and sophisticated bioinformatics based on deep structure understandings has enabled us to analyze high throughput sequencing data of the immune systems such as Immune repertoire (BCR, TCR, antibodies, etc) and RNA-seq data. KOTAI is working on discoveries of new biomarkers and therapeutic compounds through the repertoire analysis.
