A specific Polymerase Chain Reaction (PCR) has been developed for the identification of goose (Anser anser), mule duck (Anas platyrhynchos x Cairina moschata), chicken (Gallus gallus), turkey (Meleagris gallopavo), and swine (Sus scrofa domesticus) in foie gras. A forward common primer was designed on a conserved DNA sequence in the mitochondrial 12S(More)
An indirect enzyme-linked immunosorbent assay (ELISA) has been developed for the species identification of grouper (Epinephelus guaza), wreck fish (Polyprion americanus), and Nile perch (Lates niloticus) fillets. The assay was performed in two different formats, microtiter plates and immunostick tubes, and uses polyclonal antibodies raised in rabbits(More)
Enzyme-linked immunosorbent assay (ELISA) and PCR techniques have been developed for the detection of spoilage yeast species in dairy products. Polyclonal antibodies against live yeast cells (AY) were raised in rabbits by inoculation of a mixture of 10 yeast species frequently associated with dairy products spoilage. AY antibodies were used for the(More)
Composites of multiwalled carbon nanotubes with poly(ethylene terephthalate) (PET-MWCNT) with up to 3 vol% MWCNTs were prepared and characterized by broad-band AC conductivity and dielectric spectroscopy up to the infrared range using several techniques. A very low electrical percolation threshold of 0.07 vol% MWCNTs was revealed from the low-frequency(More)
Composites formed by a dielectric ceramic or polymer matrix and a conductive filler are very interesting materials since their physical properties, such as optical, electrical and magnetic properties as well as tribological, corrosion-resistance and wear properties can be tailored, which makes them attractive for many new electronic, optical, magnetic and(More)
Polymerase chain reaction amplification of a conserved region of the α-actin gene has been used for the specific identification of goose (Anser anser) and mule duck (Anas platyrhynchos×Cairina moschata) foie gras. Universal primers were used for the amplification of a DNA fragment containing three introns and four exons of the α-actin gene in goose and mule(More)
Identification of fish species adulteration is important for consumer protection and the enforcement of food-labeling laws. A monoclonal antibody (MAb) generated against soluble muscle proteins from grouper (Epinephelus guaza) has been used in two indirect enzyme-linked immunosorbent assay (ELISA) formats (microtiter plates and immunostick tubes) for the(More)
