Protein Detection and Analysis

Protein detection and analysis techniques are used to determine the quantity and purity, expression, post translational modification, structure, identification and location of proteins. 

Each protein has a unique sequence of amino acids, which in turn determines the 3 dimensional structure and function of the protein. The structural differences, along with size, charge and expression levels can be detected by a range of techniques to identify, detect and analyse the proteins. 

Common analysis techniques include electrophoresis, chromatography, mass spectrometry, crystallization, visualization via labelling and light scattering.

Common detection methods involve colorimetry assays such as simple Bradford protein quantitation, or ELISA. More sensitive quantitation assays utilize fluorescence labels. These methods can be microplate reader based, microscope based or in the case of western blots, far IR based imaging technology.

LI-COR Biosciences is a leading innovator in systems for drug discovery, protein research, and small animal imaging.

Odyssey Near Infra Red (NIR) imaging platforms provide consistent, accurate digital images. NIR fluorescent imaging gives you low membrane fluorescence and high sensitivity. Over 6 logs of linear dynamic range allows both strong and faint bands to be captured in a single image with no saturation, with two channel multiplex fluorescence allowing multiple targets per lane. 

Odyssey M  applications include visible fluorescence, fluorescent proteins, bioluminescence, chemiluminescence, colorimetry, H&E staining, cell viability, cell proliferation, apoptosis and many more.

Odyssey DLx applications include Western blots, cell-based assays, protein arrays, gel shift assays, tissue section imaging, and more are at your fingertips with near-infrared (NIR) fluorescence on the Odyssey CLx. 

Odyssey XF applications include NIR western blots, enhanced chemiluminescent (ECL) western blots and DNA gel documentation.
