In this video, we describe a protocol for genetically engineering glioma cells to express infrared fluorescent protein or iRFP. These fluorescent-tagged glioma cells hold utility in deep tissue imaging to understand the development of brain tumors.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Labeling of Glioblastoma Cells with FP635 or FP720 Construct Produce and purify lentivirus according to the protocol described below: Observe the dishes seeded on Day 1. When cells are 80–90% confluent they are ready for transfection. NOTE: The cells should still have ro…
