Genedata have released Genedata Expressionist 13.0. A new, flexible, user-definable approach to peptide mapping and sequence variant analysis (SVA) reduces false-positive annotations while maximising sensitivity, enabling best-in-class molecule characterisation—important for next-generation Multi-Attribute Method (MAM) implementations. Advanced iterative review and commenting capabilities together with insightful visualisers that streamline the curation of peptide mapping results. Further, curated results can now be easily incorporated as custom libraries and leveraged in downstream MAM monitoring processes, aiding automated quantification of Critical Quality Attributes (CQAs). Increased configurability allowing customised reporting and preventing time-consuming report reformatting. A unique integrated report approval process with signing functionalities is useful for MAM deployment in regulated environments.
