Some remarks about FLUORESCENCE

In standard light microscopy FLUORESCENCE is clearly one of the most challenging methods. It requires a clear understanding of the scientific background as well as a proper microscope setup: there are many options to miss a satisfying image result. As the costs of a traditional Mercury illumination setup (still the most flexible approach) are remarkable, a beginner in FLUORESCENCE should take his time to evaluate the adequate microscope & filter hardware.

Learning from rats

The rat proves science daily services in areas such as surgery, cancer, heart disease, embryology, diabetes, paraplegia, addiction etc. In research, in the twentieth century, the rat has been partially displaced by the mouse, which is smaller, propagates faster and is easier to manipulate genetically. But because of its greater pharmacological similarity with humans and his larger body - useful in surgeries – the rat has maintained himself in the lab.
