What is bioluminescence imaging?
Bioluminescence imaging is a technique used to visualize and quantify biological processes in live animals by detecting light emitted from luciferase-expressing cells.
How does the luminoscore method work?
The luminoscore method quantifies bioluminescence by measuring photon flux from regions of interest in captured images, allowing for easy comparison of tumor burden.
What are the advantages of using the luminoscore method?
It simplifies the imaging process, requires no complex calculations, and can be set up in any facility with a bioluminescence imager.
How quickly can the analysis be performed?
Once the imaging procedure is completed, the analysis can be performed in about two minutes per animal.
What precautions should be taken when performing this procedure?
Proper sterilization of instruments and careful handling of small animals are essential to ensure safety during the procedure.
