Abstract

The object of the present invention is to provide an agent for specific adsorption of type 5 adenoviral vector to undifferentiated blood cells which enables infection with a viral concentration that does not impart toxicity to undifferentiated blood cells, without requiring the construction of a new viral genome, or special modification of viral particles such as biotination, etc. The above objective has been achieved by providing a polypeptide which has affinity for both adenovirus and undifferentiated blood cells. Use of the polypeptide of the present invention enables improved efficiency of adenoviral vector-mediated gene transfer of any gene to undifferentiated blood cells, and there is provided a method of introducing any gene for which transient expression in these cells is desired. In particular, the method is useful for intracellular DNA recombination by transiently expressing site-specific recombinase, and for induction into any cells of different lines by transient expression of master genes.
