We do a lot of imaging of primary neuronal cultures in our lab to study the cellular and molecular basis of circadian rhythm and the CELENA S has made a significant difference to our workflow. Being able to image or even quickly scan our samples directly in our own lab has been amazing. The CELENA S is highly sensitive to fluorescence signals, so has been an excellent solution to our needs. I highly recommend this product to anyone who does a lot of fluorescence cell imaging.
