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.
VWR®, Loading dye base
Supplier: VWR Chemicals
This loading dye base is used for custom loading buffer preparation. It is a concentrated solution containing patent blue, bromophenol blue and amaranth tracking dyes, which migrate at approximately 4 000, 400 and 10 bp, on a 1% agarose gel, respectively.

VWR®, Nucleic acid loading dyes
Supplier: VWR Chemicals
Designed to optimise loading nucleic acids in agarose gels, the loading dye imparts colour to the sample to facilitate the loading process and increase the density of the sample to ensure efficient sample distribution into each well. The dye migrates independently from the sample, allowing estimation of the migration of nucleic acids.

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.
