Fluorescein refractive index
WebFor maximum clarity, detail, and contrast, the refractive index (RI) of the mounting medium should be close to that of glass (1.5) or the sample’s fixed/dried protein layers (1.53). VectaMount has an RI of 1.49 when dry and VECTASHIELD mounting media has an RI of ~ 1.45 – both superior to other commonly used reagents (e.g. Fluoromout-G has ... WebThe yield of fluorescein in 0.1 N NaOH(aq) is 0.925+/-0.015, and for rhodamine 6G in ethanol, it is 0.950+/-0.015. In both cases, the solutions are assumed to be in the limit of …

WebRefractometer —which measures the refractive index of the antifreeze solution, and Test strips—specialized, disposable indicators made for this purpose. Both specific gravity and refractive index are affected by temperature, although the former is affected much less catastrophically. WebAn 800-nm Ti:Sapphire femtosecond laser with a 100-fs pulse duration and 80-MHz repetition rate was used to perform IRIS in each piece, creating several refractive index (RI) modification lines at different speeds (between 0.1 and 5 mm/s). The lines were 1 mum wide, 10 microm apart, and approximately 150 microm below the tissue surface.
