Fluorophores microscopy
WebHaving a bright fluorophore means that you can use less excitation power and/or shorter exposures to collect the needed photons for your microscopy image. Less light exposure will also translate to less photobleaching or phototoxicity! Let’s take a look at eGFP vs mNeonGreen again for their brightness comparison. WebFluorescent dyes (also known as fluorophores/reactive dyes) may simply be described as molecules (non-protein in nature) that, in microscopy, achieve their function by …

Did you know?
WebConventional fluorescence microscopy is performed by selectively staining the sample with fluorescent molecules, either linked to antibodies as in immunohistochemistry or using fluorescent proteins genetically fused to the genes of interest. Typically, the more concentrated the fluorophores, the better the contrast of the fluorescence image. WebIdeal fluorophores for STORM should be very bright and have a high rate of photoswitching cycles. They should also exhibit minimal photobleaching in thiol-containing buffers. With appropriate dye and buffer combinations, an optimized STORM system can generate images with 5 nm resolution.
