Abstract:
The present invention relates to a protein G variant comprising a mutated Fc binding domain, which is prepared by substituting cysteine for specific residues of the Fc-binding domain of protein G, and a method for preparing the same. Further, the present invention relates to a protein G variant comprising a cysteine mutated Fc binding domain that is site-selectively modified with a UV cross-linker. Further, the present invention relates to a method for UV cross-linking the protein G variant with antibody. The present invention relates to a protein G variant-antibody conjugate that is prepared by the above method. Further, the present invention provides a method for screening or analyzing antigens using the conjugate. Furthermore, the present invention provides a biochip or biosensor fabricated by linking the protein G variant to the surface of a solid support, and a method for fabricating the same. In addition, the present invention provides a method for immobilizing antibodies and analyzing antigens using the biochip or biosensor.
Abstract:
The present invention relates to a method for preparing an protein monolayer using a peptide hybrid for protein immobilization, more precisely a peptide hybrid for protein immobilization which has improved solubility by introducing a PEG linker and a proper reaction group to the oligopeptide having specific affinity to selected types of proteins and is designed to provide enough space between solid substrates and proteins immobilized, whereby various solid substrates treated by the hybrid catch specific proteins effectively on. The peptide hybrid for protein immobilization of the present invention facilitates the control of orientation of an antibody on various solid surfaces and immobilization of various antibodies of different origins or having different isotypes with different affinity. Therefore, the surface treatment technique using the peptide hybrid of the invention can be effectively used for the production of various immunosensors and immune chips.
Abstract:
A method for cloning and expressing a target gene by homologous recombination, and more particularly a method for cloning and expressing a target gene by homologous recombination, wherein a host cell transformed with a recombinant vector and a plasmid containing a recombinase system is introduced with a linear DNA fragment comprising a target gene and a sequence having homology to the recombinant vector. Because complicated genetic engineering steps, such as the restriction enzyme treatment and ligation of a vector and a target gene, are not required, the cloning of a gene can be performed without needing a high degree of skill, and enzyme cost can be reduced. The inventive method can be effectively used for the massive, high-speed cloning and protein expression of genes, and the disclosed pRMT-iTGR system can be used as an analytical means for improving high-efficiency recombinase.
Abstract:
A Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) is provided. A preamplifier is installed as nearest to an ion cyclotron resonance (ICR) trap as possible at a detector part in the mass spectrometer, and thermal noise generated at the preamplifier is minimized by means of a cryo-cooling system to increase a signal-to-noise ratio of ion detection signals such that an ultra-low amount of specimen can be detected, which was impossible in the related art.
Abstract:
The object of the present invention is to provide an electrode device for high frequency thermotherapy, including a main casing, an electrode needle, a first engaging part, and a guide unit coupled to the engaging part to be longitudinally moved relative to the electrode needle. The guide unit has a guide tube to receive therein the electrode needle to expose a tip of the electrode needle to the outside of an end of the guide tube. Thus, the exposed length of the tip of the electrode needle is varied according to a position that the guide unit is coupled to the engaging part. The electrode device may further include a three-way valve -provided between the main casing and the guide unit to supply a liquid medicine or water t a desired part of a patient body.
