Typical costs: 1  Costs for a groom's cake are similar to those for wedding cakes, ranging from $1-$2 or less per slice for a relatively straightforward single-tier or sheet cake, to $8-$10 or more a slice for elaborate cakes with fondant, gum paste and sugar decorations or fruit.
Immunofluorescence microscopy is used to localize specific constituents in tissue sections or immobilized cells using fluorescent tags as labels.
Fluorescence imaging (a type of PL) is often employed in the biological sciences, where fluorescent tags are used to reveal the presence and distribution of molecular species. However, this approach is more invasive than Raman analysis, which is typically tag-free. Renishaw's inVia confocal Raman microscope can be used to generate images of fluorescent tags, but more commonly provides valuable tag-free chemical information.
