Barviva

Overcome normal optical limitations in microscopic studies by highlighting specific structures with stains and reagents and then protect samples with fixatives. The fast-acting dyes create strong contrasts between cell components for easier detection or analyses. Sensitive attractions to certain organelle or cellular components differ among offered stains, allowing precise testing modifications. Flexible in use, ready-to-use stains may be handled manually or in conjunction with automatic equipment.

Fluorescence antifade mounting media and CoverGrip™ coverslip sealant, EverBrite™

Fluorescence antifade mounting media and CoverGrip™ coverslip sealant, EverBrite™

Supplier: Biotium

EverBrite™ mounting media are anti-fade mountants for preserving fluorescence during microscopy. EverBrite™ mounting media prevent rapid photobleaching of fluorescein, rhodamine, and cyanine based dyes and are optimally formulated for use with Biotum’s CF™ dye conjugates. Unlike Vectashield® EverBrite™ mounting media is compatible with Cy® dyes such as Cy®2, Cy®3 and Cy®5. EverBrite™ mounting medium is a wet-set medium while EverBrite™ hardset mounting medium cures overnight to form a hard permanent seal with the coverslip, eliminating the need to seal coverslip edges with nail polish or other sealants. Both formulations are available with DAPI for blue fluorescent nuclear counterstaining without an additional staining step.
