Continuing from our first article on lasers for confocal microscopy, we will now discuss two specialized types of lasers: lasers for two-photon excitation and tunable, white light lasers. We will also discuss the applications of the two lasers. Lasers for Two-Photon Excitation The two-photon absorption phenomenon was first described for microscopy in 1931. Here, the…
Adherent cell fixation is a crucial step in preparing cells for microscopy and imaging, ensuring that cellular structures are preserved for detailed analysis. Read our 8-step guide on how to effectively fix adherent cells to your microscope slides, including tips on sterilization, coating, and fixation methods, right here.
Are you an assiduous biologist who prefers label-free imaging methods for biological samples analysis? Raman spectroscopy offers you a wonderland of imaging technique with unlimited benefits. To start with, Raman Spectroscopy is a spectroscopic technique based on inelastic scattering of monochromatic light usually from a laser in the visible or near infra-red part of electromagnetic…
Dichroic Mirror/Filter This is a semi-reflective filter which can also be referred to as ‘dichromatic beam splitter’. Unlike the Longpass filters which absorb light which is not transmitted (see Part 1 of the Glossary), these filters reflect light at lower wavelengths and transmit light at wavelengths above the ‘cut-on’ wavelength. As beam splitters, they are…
Following on from our previous article, here are some suggestions for an old microscope (should you happen not to destroy it!). 1. Museum piece Start your own mini scientific instruments museum. Before you know it, you be raking through the old skips and dumpsters at your institute looking for exhibits. 2. Teach kids Teach your…
Colocalization blues (and reds and greens) Trying to find if and where two epitopes co-localize (or, to be more precise, where they are found in close proximity) may seem easy at first: 1) Bind your two epitopes with primary antibodies from two different species, 2) bind these primary antibodies with two secondary fluorescent antibodies, one…
