Agar Scientific has announced the latest additions to the Citifluor range of antifadant mountant solutions for use in sample preparation for fluorescence microscopy. The new light-curable uv-mountants will help in cases where specimens move around or change shape on the slide thus making it difficult to home in on the area of interest. These new UVM solutions readily cure with desk-lights in 2 to 3 minutes, without having vacuoles. The solutions are stable and hence do not form stringy jelly-like material. Citifluors UVM mountants are water miscible prior to curing, are totally free of organic solvents such as xylene and are compatible with a wide range of aqueous buffers.
