Abstract

This video demonstrates an in vivo immunofluorescence localization (IVIL) technique to study the biodistribution of tumor-targeting antibodies in a murine model of breast cancer. Upon the intravenous injection of a tumor-specific antibody in the mouse, the tumor is surgically isolated, and the localization of the antibody within the tumor tissue is confirmed via ex vivo immunostaining.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Transgenic mouse model of breast cancer development Observe mice from the desired cancer model for the appropriate tumor growth via palpation or caliper measurement before proceeding. NOTE: Here, the transgenic murine model of breast cancer development (FVB/N-Tg(MMTV-PyMT)634Mul/J) (MMTV…
