Immunofluorescence microscopy is used to localize specific constituents in tissue sections or immobilized cells using fluorescent tags as labels.
Biology. Multiphoton microscopy is a powerful and versatile technique, applied in numerous fields in biology, such as neurology or embryology. It relies on an ultrafast laser to excite fluorescent molecules or proteins.t-Pulse is an ideal excitation source for multiphoton microscopy.In addition to its small size and ease of use, its infrared wavelength minimizes autofluorescence, scattering in biological tissues and cell toxicity.t relies on an ultrafast laser to excite fluorescent molecules or proteins. t-Pulse is an ideal excitation source for multiphoton microscopy.
