Image Low-Abundance Endogenous Proteins
Bioluminescence enables the imaging of low-abundance endogenous proteins. Due to the lower photon flux generated through bioluminescence, very few photons are required to observe a reporter tag. Though the low photon flux requires significantly longer exposure times depending on expression level when compared to fluorescence imaging, there is minimal background noise with bioluminescence imaging due to the lack of autofluorescence and autoluminescence in samples.
Relative Luminescence Units (RLU) are commonly used on a plate reader to indicate lower expressing proteins. Due to the signal-to-noise background of bioluminescence, one can observe very low expression targets by simply exposing the sample for longer periods of time.
Imaging low-abundance proteins through bioluminescence. Panel A. Low-abundance endogenous proteins show lower luminescent signals. Relative luminescent units (RLUs) from NanoBiT®-fusion proteins show a 2 log range in luminescent signal between high-abundance (CFL) and low-abundance (HDAC6) endogenous proteins. Panel B. Images of low- and high-abundance endogenous NanoBiT®-fusion proteins captured on the GloMax® Galaxy. HiBiT was inserted into the genomic locus of the target proteins via CRISPR/CAS9 in HeLa cells. LgBiT was expressed ectopically, and binary complementation yields the target protein-NanoBiT® fusion. Image of the high-abundance CFL required a 1-minute exposure. Image of the low-abundance HDAC6 required 3-minute exposure.
Monitor Protein Kinetics Over Time
One of the major benefits of bioluminescent imaging is the inherent stability and sustainability of the bioluminescent signal, which unlike fluorescent tags, does not require external excitation. This lack of external excitation reduces the risk of phototoxicity and photobleaching, common issues that can adversely affect cell viability and signal integrity over time.
Bioluminescent tags allow repeated imaging sessions over days, weeks or months without altering the physiological state of the system under study. Also, subtle changes in bioluminescent signal reflective of protein changes are more easily observed due to the lower photon flux of bioluminescence. This is optimal for studying targeted protein degradation.
Targeted protein degradation over time. HEK293 cells expressing endogenous HiBiT-tagged GSPT1 and stably expressing LgBiT were treated with CC-885 degrader or DMSO control treatment. Assayed with Nano-Glo® Vivazine™ Live Cell Substrate and imaged over 5 hours using GloMax® Galaxy with the Stagetop Incubator/Controller, GloMax® Galaxy.
