Thermo Scientific Pierce EDC is a carboxyl- and amine-reactive zero-length crosslinker. EDC reacts with a carboxyl group first and forms an amine-reactive O-acylisourea intermediate that quickly reacts with an amino group to form an amide bond with release of an isourea by-product. The intermediate is unstable in aqueous solutions and so two-step conjugation procedures rely on N-hydroxysuccinimide (NHS) for stabilization. Failure to react with an amine will result in hydrolysis of the intermediate, regeneration of the carboxyl, and release of an N-substituted urea. A side reaction is the formation of an N-acylurea, which is usually restricted to carboxyls located in hydrophobic regions of proteins.

Food safe kits provide a simple, reliable, and rapid procedure for detecting the presence of an animal species in meat and meat products. The assay is based on 5’ nuclease Real-Time PCR reactions to amplify a unique genomic sequence in the target organism. According to European Commission Directive 2002/86/EC, food ingredients have to be declared. In the case of meat and meat products, the animal species has to be disclosed on the label. Moreover, the species autenticity can be highly relevant to consumers for economic, medical, cultural and religious reasons. Fraudulent substitution of cheaper meats in place of more expensive species, the inclusion of meat in non meat (vegetarian) products and the presence of allergens in food products are clear examples for the importance of this issue (Ballin, 2010; Dooley et al., 2004). Several methods are based on identification of proteins by means of electrophoretic and/or immunological methods. However, these methods are not reliable for application in highly processed and heated products due to the protein deterioration. DNA is more stable than proteins during processing and although it can be fragmented by several processes, modern DNA methodologies like PCR-based techniques still allow the identification of DNA from the different species present in a sample (Lockley & Bardsley, 2000). Real-Time PCR techniques are especially suitable for these products because small fragments of DNA can still be amplified and identified with high sensitivity and specificity (Dooley et al., 2004).

This range of portable autoclaves are designed for safety and reliability, yet remain easy to use and maintain. They are fitted with an automatic cut-out to prevent them boiling dry. The lid is removable for full width access, items can either be placed in the inner liner provided or in accessory dressing drums or basket. All models are heated with a 2 kW single internal element. Temperature is controlled by the VARIO time and temperature controller and a Pt 100 thermocouple. The VARIO cycle control features four preset cycles and one variable cycle. The variable cycle is stored in permanent memory so it can be recalled. The control panel shows countdown sterilisation time and current temperature. The end of the sterilisation cycle is signalled by an audible alarm. After the sterilising period, a condensing vacuum is drawn to aid drying. This is particularly useful for dressings and drapes.
