Sapphire™ NIR-Q Biomolecular Imager

Sapphire™ NIR-Q Biomolecular Imager

Cambridge Bioscience offers a laser-based NIR fluorescence scanner platform enabling total protein normalisation for more efficient and better quality quantitative Western blotting workflows.  Combining all the advantages of the highly sensitive, low background and fast-scanning Sapphire™ NIR, the Sapphire™ NIR-Q has two channels for multiplex protein detection and a third channel for total protein detection.

Benefits Of Using The Sapphire™ NIR-Q Biomolecular Imager Sapphire Open
• 658 laser & 784 laser (both suitable for detection of modified or unmodified proteins) & a 520 laser for total protein normalisation & dye flexibility
• Detect 2 proteins & normalise to a HKP loading control
• Detect 2 proteins & normalise to a total protein stain
• Detect 2 proteins & normalise to a total cell stain
• Sapphire Capture software for high quality yet simple image capture
• High resolution image capture - down to 10 microns
• High sensitivity for lower limits of detection (femtograms)
• Ultra-wide dynamic range for accurate quantification
• Low & high abundance samples quantified simultaneously

Total Protein Normalisation
General housekeeping proteins have been used widely for normalisation when quantifying Western blot (WB) bands. However, journals now moving towards a preference for total protein normalisation for quantitative WB. Adding total protein staining to the Western blotting process can complicate an already time-consuming, multi-step workflow. It may also require stripping and re-probing of the blot if the scanner does not contain enough channels to image everything at once.

For researchers needing to scan only in the NIR fluorescence range, the Q-module addition to the Sapphire™ NIR biomolecular imager adds a third channel for visualising total protein staining (with Cy3 dyes or AzureRed fluorescent protein stain) and then probing for two proteins using the two NIR channels.
