QCM-D Study of Molecular Conformational Effects on Protein - DNA Interactions

20 Jul 2016

This application note describes a study in which Quartz Crystal Microbalance with Dissipation (QCM-D) technique is utilized to study viscoelastic characteristics of biomolecular films, which in turn can be related to molecular conformation. QCM-D monitoring is a surface sensitive technique for assessment of mass and viscoelastic properties of thin films. QCM-D analysis using the Q-Sense QCM-D from Biolin provided conformational information on estrogen receptor - DNA complexes, which are believed to be of importance in understanding subsequent gene transcription.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.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.
