T-47D-EGFP cells are a genetically modified human breast cancer cell line derived from T-47D cells, expressing enhanced green fluorescent protein (EGFP). This allows for easy visualization and tracking of the cells in vitro and in vivo., The provided information includes the passage number, quantity, contact person, and date, which are essential for maintaining consistent experimental conditions and tracking the cell line's history. These cells are commonly used in fluorescence microscopy, flow cytometry, and cell-based assays to study cell behavior, protein localization, and drug responses.
