A dye for FIRM – Fluorophore-Infiltrated Resin Microscopy

A dye for FIRM – Fluorophore-Infiltrated Resin Microscopy

FIRM is a fluorescence staining method that provides EM-like images with standard fluorescence microscopes. FIRM (Cresyl Fast Violet) provides higher contrast of fine subcellular structures than typical bright-field stainings of semithin sections, e.g. toluidine blue. Suitable for epoxy (e.g. EMBed812(Epon)) or acrylate resins (LR White).
