Luciferase+GFP Dual-Labeled Cancer Cell Lines
GeneCopoeia’s pre-made labeled cancer cell lines are dual-labeled with luciferase and GFP. Robust luciferase expression permits highly sensitive, non-invasive detection of cancer cell growth and progression in vivo, beginning soon after injection. In addition, GFP expression is useful for in vivo tumor monitoring without the need for substrate perfusion, or for in vitro visualization and immunocytochemistry. Choose from among 34 pre-made lines from various tumor types, including breast, liver, pancreas, and colon. GeneCopoeia also carries stable cell lines single-labeled with GFP.
Applications
- Study tumor cell properties using biochemical and genetic methods in vitro.
- Monitor tumor growth, progression, and metastasis in vivo in response to a variety of environmental stimuli, drugs, and other therapeutic treatments.
In vivo monitoring of tumor growth and metastasis provides a powerful means for studying cancer properties and the development of effective therapies. Mouse models created with tumor xenografts, resulting from subcutaneous or tail vein injection of cells, have long been used for such purposes. However, without a convenient means to visualize cancer progression in these animals, invasive surgical procedures are required in order to estimate the size and weight of primary and metastatic tumors, and cannot be used for early stages in tumor development. Surgery often requires sacrificing the animals, leading to the need for large numbers of individuals and increasing the cost and risk of sampling errors.
