Using MST to Analyze the Binding of Nanobodies and Nanobody-Fc Fusion Proteins to Human CD38

17 Feb 2017

Antibody affinities play an important role in diagnostic, basic research and medical applications. Conventional antibodies are composed of two heavy and two light chains. Both chains contribute to binding of the antigen by their variable domains. In addition to conventional antibodies, llamas produce functional heavy chain antibodies that lack light chains and interact with antigens solely via the variable domain of the heavy chain, designated VHH. Recombinant VHHs are also called single domain antibodies or nanobodies because of their size in the nm range. This application note compares the binding of nanobodies and nanobody-Fc fusion proteins to human CD38 using MicroScale Thermophoresis (MST).

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. Find the best protein purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Antibody ArraysBiopharmaceuticalsBiopharmaceuticals are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or for in vivo diagnostics. The most well known example of a biopharmaceutical product, and the first to be approved for therapeutic use, was recombinant human insulin.Protein StructureProtein structure refers to the three-dimensional arrangement of amino acids in proteins, determining their function. Understanding protein structure is key in drug discovery, enzymology, and molecular biology. Explore protein structure analysis tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Recombinant ProteinsEngineered AntibodiesEngineered antibodies are modified to enhance specificity, stability, and functionality for therapeutic and diagnostic applications. These antibodies are central to immunotherapy and biomarker detection. Compare engineered antibody solutions in our directory to find top products and reviews.Protein BiologyThe analysis of protein expression, identity and function is vital for many areas of life science research and drug discovery. Some of the most commonly used techniques in protein analysis include Western blotting, electrophoresis and mass spectrometry.
