Piezoelectric bio-chip for detecting pathogen of mad cow disease and thereon preparation

The present invention relates to the device for animal inspection and quarantine and the preparation method thereof. The present invention is especially applicable to the detection of the pathogen of bovine spongiform encephalopathy (BSE) (also known as “mad cow disease”). The present invention employs a piezoelectric chip, a microelectrode array and a common electrode fixed on the lower side surface and upper side surface of the piezoelectric chip, respectively, and a BSE PrP antibody array to constitute the piezoelectric biochip for the detection of the BSE pathogen. The BSE PrP antibodies are immobilized on the electrodes of the microelectrode array in a format corresponding uniquely to the electrodes of the microelectrode array by adsorbing, bonding, cross-linking, embedding or self-assembly process. The combination of the piezoelectric biochip and a detector constitutes the piezoelectric biochip detection system for the BSE pathogen. When the antibodies react with the corresponding PrPs immunochemically, the information about the PrPs can be detected at real time by measuring the resonant frequency, and the PrPs thus can be analyzed qualitatively and quantitatively. The present invention is applicable to the early, effective and rapid detection of the BSE pathogen.

Transgenic ungulates having reduced prion protein activity and uses thereof

The invention provides cloned transgenic ungulates (e.g., bovines) in which prion protein activity is reduced by one or more genetically engineered mutations. Desirably, these transgenic bovines are also genetically modified to express xenogenous (e.g., human) antibodies. Because of their resistance to prion-related diseases such as bovine spongiform encephalopy (also known as mad cow disease), these bovines are a safer source of human antibodies for pharmaceutical uses and a safer source of agricultural products.

Assay for species sources

A family of PCR assays is disclosed for determining, both qualitatively and quantitatively, presence of material from a predetermined species source and for quantifying the amount of such material. The assays are based respectively on SINEs uniquely characteristic of pig species, cow species, chicken species, and ruminant sub-order, and having a high copy number. The assays disclosed permit rapid, inexpensive evaluation of meat samples to facilitate elimination from their diet of pork or beef by persons desiring to avoid such food sources; as well as the assay of cattle feed to determine presence therein of ruminant-source proteins, which are a potential source of bovine spongiform encephalopathy (BSE), commonly referred to as “mad cow disease.” The assays amplify the predetermined unique SINEs and the resulting amplified mixture is then evaluated qualitatively by electrophoresis on gel containing ethidium bromide or quantitatively by SYBR Green-based detection or TaqMan chemistry. The invention also extends to kits, primers, and other products used in connection with the assays. The amplicons are selected to be from about 100 to 170 bp long.

The present invention relates to a manufacturing technique of fetal bovine serum. The present invention includes the full closed aseptic collection, low temperature separation and microporous membrane filtration, which is characterized in that: the present invention carries out the caesarean section of a cow which is approximately eight months pregnant, lateral decubitus restraint method is adopted before the delivery, and the anesthesia adopts the method with the combination of general anesthesia and local anesthesia at the surgical site. The full closed aseptic cardiac puncture for blood sampling is carried out on the fetal bovine; after the collection of the blood, a large-capacity refrigerated centrifuge is used for centrifugation of 30 minutes as the rotation speed of 3400 turns per minute, and the separated serum is collected in a sterile container under the local class 100 area for rapid cryopreservation. The present invention has the advantage that: the price of the imported fetal bovine serum is higher, which reaches about 6,000 RMB per liter. The imported fetal bovine serum from the United States and Europe not only has high cost, but also has the hidden dangers of mad cow disease. The price of the fetal bovine serum which is produced by our manufacturing technique is just 4000 to 5000 RMB per liter, which completely changes the status that the fetal bovine serum in China entirely dependents on the foreign imports.
