BrightSite™ Near-Infrared Fluorescent Targeting Agents for Optical Imaging of Disease

25 Mar 2011

This application note by LI-COR Biosciences assesses the use of NIR dyes for clinical in vivo imaging. In the NIR wavelength range (700–900 nm) tissue autofluorescence is lower and light can penetrate more deeply than in visible light wavelengths. Here NIR fluorophores are used to image mice tumours and bone structure.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.BiosensorsBiosensors are devices used to detect an analyte using biological molecules specific to the analyte coupled to a detector. Biosensor instruments may be photometric, typically using surface plasma resonance (SPR), electrochemical or QCM (quartz crystal microbalance) biosensors. Biosensors should be selective, portable, robust and sensitive and have a fast response time. Systems may be manual or automated and usually have associated software.Western BlottingWestern blotting equipment is used to transfer and identify specific proteins within a sample, reveal protein modifications, as well as give a semi-quantitative estimation of their concentration. Western blotting equipment includes all apparatus necessary to transfer proteins from gel to membrane and subsequent processing steps. Protein transfer can be performed by electroblotting with wet, semi-dry and dry transfer systems onto nitrocellulose and PVDF membranes. Blocking, washing and labeling of membranes follows, involving buffers, blocking reagents, blotting / incubation trays, labeling reagents, immunoblotting assays, antibodies and conjugates. Automated equipment for these steps is available to accelerate your lab workflow. Finally, detection and imaging of proteins can be conducted using gel documentation and imaging systems.
