  • Patent number: 10881750
    Abstract: The present invention relates to a sentinel lymph node marker comprising an albumin; a radioactive isotope and/or near infrared dye which is bound to the albumin; and a visible dye which is bound to the albumin, a preparation method thereof, and a kit for multimode imaging of a sentinel lymph node to prepare the sentinel lymph node marker. The sentinel lymph node marker of the invention remains in the sentinel lymph node for a long period of time and allows for multimode imaging of the sentinel lymph node. Thus, using this marker the sentinel lymph node can be accurately identified in vivo by near infrared imaging and/or gamma imaging without incision of skin, and the location of the identified sentinel lymph node can be precisely identified with the naked eye during a surgical operation of removing the identified sentinel lymph node.
