  • Patent number: 10077468
    Abstract: The present invention relates to a PCR primer facilitating hot-start PCR by suppressing non-specific amplification at room temperature and at the same time capable of reducing significantly non-specific amplification by dominating the amplification of the PCR product rather than the amplification of the original template from the third PCR cycle, more precisely a PCR primer prepared by additionally inserting the reverse-complementary sequence to a certain region starting from the 5?-start site of the 5?-terminus of the original primer which is composed of priming sequence to anneal to a PCR template into the 5?-terminus of the original primer and a PCR method using the same.

  • Publication number: 20130273635
    Abstract: The present invention relates to a bacteriophage PA1? belonging to family Siphoviridae, characterized that it is capable of killing one or more bacteria strains selected from a group comprising Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus homonis, Shigella sonnei, Listeria monocytogenes and Streptococcus pneumonia, and contains a full-length genome of SEQ ID NO: 1. According to the present invention, the bacteriophage PA1? can be used to kill said bacteria and reduce the same effectively. Also, it can be used to remove biofilms generated by said bacteria. Especially, this bacteriophage is applicable for medical industry, food industry, biotechnology and the like, because it is a sort of virus that kills host bacteria without any adverse effect on human, animals and so on. In addition, this bacteriophage can kill noxious bacteria on target sites or target supports without any problem related with resistance development of bacteria.

  • Publication number: 20110014714
    Abstract: The present invention relates to a method for the preparation of a labeling material (labeling agent) usable for non-radioactive selective labeling of proteins produced by in vitro translation with fluorophore or biotin; and a method for selective labeling of proteins produced by in vitro translation using the said labeling material. More specifically, the present invention provides a method for preparing a labeling material usable for selective labeling of a target protein produced only from the gene added to the cell-free protein synthesis reaction mixture by an experimenter without labeling pre-existing proteins in the reaction mixture, for which only one type of tRNA prepared by in vitro transcription is used instead of “total tRNA mixture”. The present invention also provides a method for labeling of the protein produced by in vitro translation by using the labeling material prepared by the above method.
