Abstract:
A method and kit for diagnosis of toxicity and exposure for deoxynivalenol are provided to improve detection convenience and time of deoxynivalenol by detecting increase of a haptoglobin level in blood plasma. A method for diagnosis of toxicity and exposure for deoxynivalenol comprises the steps of: coating an ELISA(enzyme-linked immunosorbent assay) plate with an anti-haptoglobin antibody; adding diluted blood plasma into the plate and reacting them for a certain period; reacting the plate with a secondary antibody to determine presence of haptoglobin having the amino acid sequence of SEQ ID NO:1. A kit for diagnosis of toxicity and exposure for deoxynivalenol comprises an antibody specific to haptoglobin or its immunogenic fragment, fixed in a reaction region of a strip.

Abstract:
PURPOSE: A primer set for distinguishing four types of toxins in E. Coli and a multiplex polymerase chain reaction (PCR) kit using the same are provided to quickly and accurately detect four types of toxins (LT, STa, STb, STX2e) within two hours so as to diagnose pathogenic E. Coli in livestock. CONSTITUTION: A primer set for detecting LT (GenBank accession No. V00275) which is a type of toxin in E. Coli has a forward primer of sequence number 1 and a reverse primer of sequence number 2. A primer set for detecting E. Coli STa (GenBank accession No. AJ555214) which is a type of toxin in E. Coli has a forward primer of sequence number 3 and a reverse primer of sequence number 4. A kit for determining the type of toxins selected among LT, STa, STb, and STX2e contains the primer set. LT, STa, STb, and STX2e are detected using the kit.
Abstract:
PURPOSE: A PAM-pCD163 cell line for isolating porcine reproductive and respiratory syndrome(PRRS) virus is provided to develop a vaccine and to prevent PRRS. CONSTITUTION: A PAM-pCD163 cell line is prepared by expressing pCD163 in PAM cells through a retrovirus prepared by transforming plasmid containing pCD163 genes into HEK293 cells. The plasmid is pFB-Zeo-pCD163. A method for preparing the cell line comprises: a step of performing transfection of VSV-G glycoprotein and MMLVgag/pol gene, and a plasmid containing pCD163 into HEK293 cells to prepare retrovirus; and a step of inoculating the retrovirus into the PAM cells.
Abstract:
PURPOSE: An RNA resistance RNA aptamer which suppresses PCV2 replication is provided to ensure specific bond to a target protein and to be used in an antiviral agent. CONSTITUTION: An RNA resistance RNA aptmer contains an oligonucleotide having a base sequence of sequence number 1 or 2 in which 2' hydroxyl group of uracil and cytosine is substituted with a fluorine group. An antiviral agent against PCV2 contains RNA atpmer and an antiviral material which is structurally connected to the RNA aptamer. The antiviral material is siRNA.
