Leveraging Mass Spectrometry to Efficiently Deliver Precise and Actionable Insights into Biologics (RNA / DNA, Oligonucleotides, Conjugates, and Peptides / Proteins).
Overview
mmBiologics leverages mass spectrometry to efficiently deliver precise and actionable insights into biologics. The solution provides unified XIC generation / quantification, deconvolution and sequencing*, with visualizations for deeply interrogating datasets. Multiple datasets can be batch processed via workflows that automatically perform LC peak detection, quantitation, deconvolution and sequencing*.
Overview
Spacer Fidelity Assessments of Guide RNA by Top-Down Mass Spectrometry
ABSTRACT: The advancement of CRISPR-based gene editing tools into biotherapeutics offers the potential for cures to genetic disorders and for new treatment paradigms for even common diseases. Arguably, the most important component of a CRISPR-based medicine is the guide RNA, which is generally large (>100-mer) synthetic RNA composed of a “tracr” and “spacer” region, the latter of which dictates the on-target editing site as well as potential undesired off-target edits. Aiming to advance contemporary capabilities for gRNA characterization to ensure the spacer region is of high fidelity, top-down mass spectrometry was herein implemented to provide direct and quantitative assessments of highly modified gRNA. In addition to sequencing the spacer region and pinpointing modifications, top-down mass spectra were utilized to quantify single-base spacer substitution impurities down to U and U > C substitutions, and created a de novo sequencing strategy to facilitate the identification and quantification of gRNA impurities with highly dissimilar spacer regions.

Sequence analysis provides an overview of all detections based on their ion, position, and charge state. The unique scoring algorithm scores the entire isotopic envelope, improving the detection and qualification of ion matches. The user can filter scan, charge state, score, consecutive matches, and monoisotopic matches. All plots and tables are exportable in common formats (PNG, SVG, CSV).
When viewing, the best ion match can be found by clicking on the top row. All plots and tables are exportable in common formats (PNG, SVG, CSV).
Not only are scores for each sequence analysis produced, but comparisons across charge states and scans can be made. This gives an objective comparison when studying sequences detected in various samples. All plots and tables are exportable in common formats (PNG, SVG, CSV).
XICs are presented in an intuitive format enabling quick evaluation of the XIC and setting of the RT range for calculating an accurate area under the curve. All plots and tables are exportable in common formats (PNG, SVG, CSV).
The XIC wizard allows for quickly generating an analysis of all possible XIC ranges for a given molecule.
The auto deconvolution feature provides a variety of algorithms to efficiently search MS and UV data. Fixed retention time (RT) ranges and automatic peak detection (valley to valley) of MS and UV data are available for batch signal averaging and deconvolution. Results are presented in an intuitive user interface for easy interpretation. Multiple files can be processed in parallel and distributed and scaled across cloud resources. All plots and tables are exportable in common formats (PNG, SVG, CSV).
Automatic annotations via database lookups for known molecules are provided when evaluating deconvolution results. All plots and tables are exportable in common formats (PNG, SVG, CSV).
