A Technique to Assess the In Vivo Localization of Tumor-Specific Antibodies

Abstract

Source: Shivange, G., et al. Analyzing Tumor and Tissue Distribution of Target Antigen Specific Therapeutic Antibody. J. Vis. Exp. (2020).

This video demonstrates a technique to study the in vivo localization of tumor-specific antibodies in a mouse tumor xenograft model. Upon subcutaneously injecting cancer cells into mice for tumor formation, fluorescently-labeled antibodies are injected that bind to tumor-specific receptors, enabling in vivo assessment of antibody localization via imaging.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Expression and purification of antibodies Maintenance of Chinese hamster ovary (CHO) cells Grow CHO cells in FreeStyle CHO Media supplemented with commercially available 1x glutamine supplement at 37 ˚C shaking at 130 rpm with 5% CO2 using delong Erlenmeyer flasks either glass or disposable.<…
