You searched for: Stains
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™
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.

Silver stain, FOCUS™ FASTsilver™
Supplier: G-Biosciences
FOCUS™ FASTsilver™ produces crystal clear backgrounds and maximal peptide recovery needed for critical analysis by mass spectrometry. Complete proteolytic digestion and recovery of peptides is required for optimal analysis, however silver ions in traditional silver staining kits inhibit proteolytic digestion. In addition, glutaraldehyde, a common sensitiser in silver stains, modifies peptide lysine residues preventing complete digestion and recovery.

Vectashield® mounting medium
Supplier: VECTOR LABORATORIES
Vectashield® Mounting Medium is a unique, stable formula for preserving fluorescence. It is superior to other anti-fading reagents or mounting media for fluorescence microscopy. Some agents retard the rate of fading, but their initial application gives a severe reduction in emission. Others give a good initial reading but bleach upon illumination. Vectashield® Mounting Medium combines both advantages into one product. It provides strong initial fluorescence and retards photobleaching over time. Vectashield® Mounting Medium is supplied in a bottle fitted with a cone-seal cap. A cap fitted with a drop dispenser pipette is also included. The cone-seal cap can be replaced with the drop dispenser cap for routine use and during storage. Mounted slides should be stored at 4 °C. The fluorescence will remain for many weeks.
