Agar Scientific offers a wide range of chemicals and accessories for grid and en-block staining including Lead citrate and Uranyl acetate which are the most widely used stains for ultrathin sections. We also offer selection of negative stains including Phosphotungstic acid and Methylamine tungstate. Methylamine tungstate does not damage virus particles and is consequently valuable for staining delicate viruses.
Various accessories and grid holders facilitate the staining of multiple grids. A simple numbered grid holder and handle enables the staining 25 grids, and fits into standard Petri dishes for immunocytochemistry and post staining.
