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.

Glycoprotein stain
Supplier: G-Biosciences
The stain uses an enhanced Periodic Acid-Schiff (PAS) method for detection of glycoprotein sugars. The supplied agent first oxidises the cis-diol sugar groups to aldehydes. The aldehyde groups react with the sensitive glycoprotein stain solution forming Schiff bonds and producing strong magenta colour bands. RAPIDstain™ can be used after glycoprotein staining to detect non-glycosylated proteins and the use of the stain enhances glycoprotein staining. The glycoprotein stainis highly convenient as all the key reagents required for staining are supplied and a unique positive & negative control is included.

Epoxy Embedding Medium Kit
Supplier: SIGMA ALDRICH MICROSCOPY
The Epoxy Embedding Medium Kit is a very widely used embedding medium for electron microscopy. The embedding formulation originally published by Luft (1961) is excellent for both plant and animal tissues. Due to the low viscosity of the resin, it penetrates the tissue specimen faster than Araldite and other polymers. It hardens easily and uniformly at low temperatures with the addition of dodecenylsuccinic anhydride (DDSA), methyl nadic anhydride (MNA), and the accelerator 2,4,6-tris(dimethylaminomethyl)phenol (DMP-30). Slight shrinkage may occur during curing. This kit is useful for embedding a variety of tissues as a wide range of hardness can be obtained with this resin to suit a specific tissue type by using two different anhydride curing agents (DDSA and MNA).

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.

Water-free mounting medium, Neo-Mount®
Supplier: Merck
Water-free mounting media, such as Neo-Mount®, should be used for permanent mounting and long-term storage of samples. Slides processed in pathologyl laboratories need to be stored up to 10 years, whereby the staining results need to be stable and fading-out is not acceptable. Neo-Mount®, anhydrous mounting medium for microscopy is an extremely colour-stable mounting medium for microscopy, which is produced with solvents based on mixtures of aliphatic hydrocarbons. It contains an aromatic-free substitute for xylene, thus, Neo-Mount® needs to be combined with Neo-Clear® exclusively. Xylene must be avoided in the mounting step, as it will cause the slides to become cloudy and streaked. In addition, by placing the dehydrated slides on filter paper for approx. 1 minute prior to mounting, any excess Neo-Clear® should be circumvented, as air bubbles might arise under the cover slip. The same pre-condition should also be met when mounting specimens using cover slip machines; in this area, Neo-Clear® can be most efficiently eliminated by incubating the slides for 1 minute in an empty slide rack.
