VSC0460 | pTet-On | Clontech | 四環(huán)素調(diào)控系統(tǒng) |
pTet-On expresses the reverse tet-responsive transcriptional activator (rtTA) from the strong immediate early promoter of cytomegalovirus (PCMV). tTA is a fusion of amino acids 1–207 of the tet repressor (TetR) and the negatively charged C-terminal activation domain (130 amino acids) of the VP16 protein of herpes simplex virus. pTet-On is similar to pTet-Off except for four amino acid changes that convert the TetR to a rTetR, and consequently, tTA to rtTA. (pTet-Off also contains several silent mutations.) pTet-On was originally described as pUHD17-1neo by Gossen et al. pTet-On can be distinguished from pTet-Off by digestion with Hind III.
