This lentiviral expression vector encodes the tdTomato fluorescent protein tag. This very bright red fluorescent protein is a genetic fusion of two copies of dTomato, which was specifically designed for low aggregation. It adopts an intramolecular tandem dimer structure that contributes to its exceptional brightness, yet it behaves like a monomer. Inserting a cDNA in the MCS upstream of the tdTomato coding sequence joins your protein of interest to the N-terminus of the tag, and allows the fusion protein to be tracked and studied in transduced cells.
To package the vector into high-titer, replication-incompetent lentivirus, we recommend using Lenti-X Packaging Single Shots and the Lenti-X 293T Cell Line. The resulting lentivirus can then be used to transduce virtually any mammalian cell type.
