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).

Listeria monocytogenes is one of the most widely distributed foodborne pathogens in the world and is responsible for severe infections in immunocompromised persons, pregnant women and neonates. As a result, the mortality rate in infected individuals is high despite the relatively low number of cases around the world. Listeria infections (listeriosis) can result in anything from mild gastroenteritis to severe cases of sepsis, meningitis, encephalitis or abortion. Due to the ubiquitous distribution of Listeria and their capability to grow at refrigeration temperatures ( 2 to 8 °C), food products constitute one of the main sources of infection. Listeria is a genus of Gram-positive, non-sporeforming, rod-shaped bacteria. Of the six known species of the genus Listeria, Listeria monocytogenes deserves particular mention as a human and animal pathogen; L. ivanovii is only pathogenic in animals, while L. innocua, L. seeligeri, L. grayi, and L. welshimeri are considered harmless environmental bacteria. Consequently, food legislation in many countries specifies strict limits for Listeria spp. or Listeria monocytogenes. In the conduct of risk-related quality controls in food, tests should be run for L. monocytogenes, and for the Listeria Genus in general. The presence of Listeria – in particular of L. innocua – is an indicator for critical hygienic conditions in the production process. Innovative, rapid tests make screening for pathogenic organisms easier. The one-step format reduces the possibility of errors during handling.

The Variostat can control the temperature of any size bath from −30 to 150 °C. The special construction gives the user flexibility in a number of different applications. With the infinitely controllable VPC pressure or suction pump, circulation in the respective bath sizes can be adapted for optimum results. Furthermore, the pump pressure for external applications can be set and controlled using the menu control with an optional pressure sensor. Insulated bath vessels are available in stainless steel as an accessory in three standard sizes or can be custom made with any desired dimensions.

The Owl™ B2 EasyCast™ mini horizontal gel system provides flexibility in a small footprint and is available with or without buffer exchange ports. The Owl™ B3 with built-in recirculation system prevents formation of pH and ionic gradients for high resolution and uniform reproducible results. The Owl™ B3 is ideal for long runs, multiple sample sets or RNA gels. It also eliminates uneven migration, band distortion or disassociation of pH dependent glycoxylated RNA molecules that can result when ionic depletion occurs. As the recirculation system is built into the buffer chamber, no external pumps, tubing or stirring bars are required.
