The present invention relates to a host cell expressing monomeric streptavidin. The host cell according to the present invention expresses streptavidin in the body, such that it is possible to visualize and monitor, in real time, the distribution of cancer tissues in vivo that the host cell has pre-targeted with a biotinylated diagnostic agent, as well as to increase the cancer-targeting efficiency of biotinylated anticancer drugs. |
