Abstract:
본 발명은 PNA(Peptide Nucleic Acid) 마이크로어레이 칩을 이용한 식중독균 검출 방법, 이에 사용되는 PNA 프로브 및 PNA 마이크로어레이 칩에 관한 것으로서, 이를 사용하면, 우수한 특이도와 민감도로 6종의 식중독균을 단시간 내에 한꺼번에 검출할 수 있으므로 용이하고 체계적인 식중독균 관리를 통한 안전한 농작물 제공이 가능하다.
Abstract:
PURPOSE: A method for detecting poisoning bacteria using a PNA microarray chip, a PNA and PNA microarray chip are provided to detect six kinds of food-poisoning bacteria with high sensitivity and specificity and to easily and systemically control the food-poisoning bacteria. CONSTITUTION: A PNA(peptide nucleic acid) probe for detecting food poisoning bacteria has a base sequence selected from sequence numbers 1-7. The PNA probe with a base sequence of sequence number 1 specifically binds to Bacillus cereus. The PNA probe with a base sequence of sequence number 2 specifically binds to Listeria monocytogenes. The PNA probe with a base sequence of sequence number 3 specifically binds to Staphylococcus aureus. The PNA probe with a base sequence of sequence number 4 specifically binds to Yersinia enterocolitica. The PNA probe with a base sequence of sequence number 5 specifically binds to Salmonella enteric. A method for detecting poisoning in a sample comprises a step of hybridizing the PROBE with the sample; and a step of detecting a signal generated by hybridization.
Abstract:
PURPOSE: A primer pair and a method for detecting Salmonella typhimurium are provided to quickly and accurately detect Salmonella typhimurium among various food poisoning bacteria. CONSTITUTION: A primer pair for detecting Salmonella typhimurium contains a primer pair of sequence numbers 1(primer name: STM 2761) and 2(primer name: STM 2762). A kit for detecting Salmonella typhimurium contains the primer pair. A method for detecting Salmonella typhimurium comprises PCR amplification using the primer pair. A PCR product is detected by DNA chip gel electrophoresis, radioassay, fluorimetry, or phosphorometry.
