Abstract: There are provided an information offering method for diagnosing breast cancer comprising: (a) separating total RNA from a cell obtained from a tissue or blood of a suspected cancer patient; (b) synthesizing a cDNA from the separated total RNA; (c) performing a real-time PCR with the synthesized cDNA by using primer pair mix and probe mix that can amplify human epidermal growth factor receptor 2 (HER2); wherein, the primer pair mix that can amplify human epidermal growth factor receptor 2 (HER2) are described as SEQ ID Nos.:1 and 2, 3 and 4, and 6 and 7 and the probe mix are described as SEQ ID Nos.: 5, 8, and 9.

Abstract: The present invention relates to a Korean-type porcine reproductive and respiratory syndrome virus (PRRSV) and a vaccine composition using the same, and a method for preventing porcine reproductive and respiratory syndrome. Korean-type porcine reproductive and respiratory syndrome virus with accession number KCTC 12096BP according to the present invention is Korean-type porcine reproductive and respiratory syndrome virus distinguished from European strains and North American strains, and a vaccine composition specific to Korean-type porcine reproductive and respiratory syndrome virus is produced, thereby preventing a Korean-type porcine reproductive and respiratory syndrome virus or specifically diagnosing the infection with Korean-type porcine reproductive and respiratory syndrome virus.
