Microsaic Systems plc, the developer of chip-based mass spectrometry (MS) instruments, has developed a novel technology to enable real-time analysis of proteins in bioprocessing applications, such as in the manufacture of biologic molecules (proteins, antibodies and peptides) for therapeutic and diagnostic uses.

The new technology is a tool for rapidly desalting and purifying protein samples prior to their analysis using Microsaic’s 4000 MiD® MS instrument. This new technology has the potential to significantly accelerate the industrial purification of biologics.

Glenn Tracey, Microsaic’s Chief Operating Officer, commented: “The benefits of Microsaic’s point of use MS technology, in combination with its patented innovation for on-line desalting, allows for the purification of the desired biomolecules in real time. In doing so, analysis times can be reduced from days or even weeks to minutes while offering the potential for significant savings on operational costs. Eight of the top ten selling drugs in 2016 were biologics and the trend for targeted biologic therapeutics is set to continue. Technologies that can accelerate and enhance their production therefore present an opportunity for Microsaic.”

Mass spectrometry is a powerful technique which allows the effective implementation of “QbD” (Quality by Design), a key industry and regulatory driver for current and future production of biologics.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.Protein QuantificationThe detection and quantification of proteins in a sample is vital across life sciences, pharmaceutical research and clinical diagnostics, and a variety of equipment is available to scientists to simplify the workflow. Proteins of interest can be easily labeled and detected on light-based detection instruments. Immunoassay kits allow you to identify a specific protein of interest and protein detection beads or antibody microarrays allow you to identify multiple specific proteins at once. Protein interactions and enzyme activity can also be monitored with protein-protein interaction assays. Additionally, the biophysical characterization of proteins is made easy with biokinetic analyzers.

Peptide research is critical in drug discovery, diagnostics, and vaccine development. Browse our peer-reviewed product directory to find the best peptides and peptide-related products, compare options, check reviews, and get pricing directly from manufacturers.Therapeutic AntibodiesTherapeutic antibodies are antibodies engineered for use in treating diseases. They can be designed to target specific antigens, blocking harmful interactions or modulating immune responses. Therapeutic antibodies are critical in treating conditions like cancer, autoimmune disorders, and infectious diseases. Explore the best therapeutic antibody products in our peer-reviewed product directory; compare options, check reviews, and get pricing directly from manufacturers.Monoclonal AntibodiesMonoclonal antibodies (mAbs) are lab-made molecules that can bind to specific antigens on cells, making them highly effective in treating cancers, autoimmune diseases, and infections. These targeted therapies are transforming the treatment landscape for many conditions. Browse our peer-reviewed product directory to find monoclonal antibodies for research and clinical applications; compare products, check reviews, and get pricing directly from manufacturers.BiotherapeuticsBiotherapeutics are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or in <i>in vivo</i> diagnostics. The most well-known example of a biotherapeutic product, and the first to be approved for therapeutic use, was recombinant human insulin.Molecular DiagnosticsMolecular diagnostics use an individual’s genetic code and gene expression to diagnose and monitor diseases. The technique is used increasingly in the field of infectious diseases and oncology, as well as areas such as coagulation, HLA typing and pharmacogenomics. Molecular diagnostics plays a pivotal role in personalized medicine.Protein Purification
