Stemolecule™ Doxycycline hyclate
Stemolecule™ Doxycycline hyclate
Stemolecule™ Doxycycline hyclate (Dox) is a broad spectrum antibiotic derivative of tetracycline and an inhibitor of matrix metalloproteinases in vivo. Tetracycline-controlled transcriptional activation is a method of inducible expression whereby transcription is reversibly turned on or off in the presence of tetracycline or one of its derivatives such as Dox1. Dox-inducible lentiviral reagents such as the Stemgent® iPSC Generation Dox Inducible Lentivirus products are used to induce the expression of virally transduced genes and generate induced pluripotent stem (iPS) cells from somatic cells (in a process referred to as reprogramming2,3) by adding Dox to the cell culture medium4-9. Stemolecule™ Doxycycline hyclate is the recommended inducer for all of the Stemgent® iPSC Generation Dox Inducible products. In the iPSC generation protocol, addition of Dox to the culture medium of transduced cells induces the reverse tetracycline transactivator (rtTA) to bind to the Tet response element and results in the transcriptional activation for each of the factors implicated in the reprogramming process. Conversely, Dox can be removed from the medium to suppress transcriptional activation of the reprogramming factors.
