    摘要: The present invention provides a method which can achieve the homologous recombination of a gene of interest selectively, and a recombinant DNA molecule produced by the method. A homologous recombination method which uses a PCR product and a linearlized vector is disposed. The PCR product comprises a sequence for a target gene and amplification primer sequences P1 and P2 on both terminal ends. The vector contains homologous recombination regions VP1 and VP2 which respectively comprises nucleotide sequences homologous to the amplification primer sequences P1 and P2 of the PCR product, and a homologous recombination region VT1 which comprises a nucleotide sequence homologous to a sequence T1 that is a part of sequence in the PCR product internal to P1 on the terminal side of VP1 and/or a homologous recombination region VT2 which comprises a nucleotide sequence homologous to a sequence T2 that is a part of sequence in the PCR product internal to P2 on the terminal side of VP2 (provided that at least one of T1 and T2 has a nucleotide sequence specific to the target gene). The method comprises subjecting the PCR product to a homologous recombination reaction to insert the PCR product into the vector, thereby producing a recombinant DNA molecule in which the PCR product of interest specifically inserted into the vector. Also disclosed a cloning method for producing the recombinant DNA molecule comprising the vector and the PCR product of interest specifically inserted into the vector by the homologous recombination method, and amplifying the recombinant DNA molecule.

    摘要: An object is to provide a TCR cloning system that enables not only bias-free analysis of TCR repertoires, but also collection of antigen-specific TCR α/β cDNA pairs and evaluation of functions thereof. There is provided a method for producing a gene of T cell receptor (TCR) specific to an antigen A, which comprises 1) the step of stimulating a group of T cells including a T cell specific to an antigen A or one T cell specific to an antigen A under a condition effective for amplification of a TCR gene; 2) the step of identifying a T cell specific to an antigen A among the group of T cells including a T cell specific to the antigen A, and sorting one T cell specific to the antigen A into a vessel; and 3) the step of subjecting the one activated T cell specific to the antigen A in the vessel to PCR to amplify a gene of TCR specific to the antigen A. According to the present invention, a target TCR gene can be cloned within a shorter time compared with that required by the conventional methods, for example, about ten days. Further, according to the present invention, genes of TCR α chain and β chain can be highly efficiently cloned. Under the conditions of the examples, a pair of a TCR α chain and TCR β chain could be obtained from stimulated T cells sorted as single cells at a ratio of 100%.
