  • Crosslinking agent, crosslinking method, method of controlling gene expression, and method of examining gene function
    Patent number: 8084625
    Abstract: The present invention provides a crosslinking agent which have photodegradable protective groups at two ends to crosslink double-stranded nucleic acid, a nucleic acid and a protein or a polypeptide, or proteins or polypeptides, in particular, double-stranded RNA; a method for crosslinking a double-stranded RNA or the like using the same; a method for regulating gene expression, which can control the expression of a target gene at an arbitrary timing and location; and a method for examining a gene function. According to the present invention, crosslinking between double-stranded nucleic acids between a nucleic acid and a protein or a polypeptide, or between proteins or polypeptides, in particular, between double-stranded RNA can be easily formed, and in addition, the crosslinking can also be easily removed, so that the expression of a target gene can be easily controlled at an arbitrary timing and location with high efficiency.
