We are pleased to offer a set of polyclonal and monoclonal anti-Tet-Repressor (TetR) antibodies, manufactured by MoBiTec. The immunogen is TetR-tetO (Accession no. P04483). These antibodies possess excellent binding properties and have been successfully tested for use in ELISA, Western blot and immunofluorescence assays. They can be used in the detection of Tet-Repressor (TetR), Tet-Repressor fusion protein (TetR-Fusion), tetracycline responsive transactivator (tTA) and reverse tetracycline responsive transactivator (rtTA). We also offer a TET-Repressor Protein as a positive control (Cat# TETR1).

TET01 is a polyclonal rabbit anti-Tet-Repressor antibody. It was prepared using TetR-tetO as immunogen, and has been purified on Protein G. It is provided as 200ul of purified antibody, lyophilized. After reconstitution to 200µl in distilled water, it can be further diluted 1:1000 for Western blots and ELISA applications. (Monoclonal antibody TET03 is recommended for immunofluorescence studies.) This antibody has excellent binding properties to TetR. Detection limits with this antibody are as follows: ELISA = 0.2ng; Western Blots = 0.8ng.

TET02 is provided as 1mg of purified antibody, lyophilized. After reconstitution to 100ul in distilled water, it can be further diluted 1:500 - 1:2000 for Western blots and ELISA applications. (Monoclonal antibody TET03 is recommended for immunofluorescence studies.) This antibody has excellent binding properties to TetR. Detection limits with this antibody are as follows: ELISA = 20-50pg; Western Blots = 0.8 - 1ng

TET03 is a mouse monoclonal antibody, IgG1 Kappa. The antibody recognizes amino acid # 37-44 and is ideal for immunofluorescence studies. TET03 is provided as 50µg of purified antibody, lyophilized. After reconstitution to 100µl in distilled water, it can be further diluted 1:100 to 1:500 for immunofluorescence studies.

TETR1 is a positive control. It is a purified 23 kDa Tet-Repressor (B) protein from E. coli transposon Tn10.

Please note: MoBiTec anti-TetR(B) antibodies were raised against TetR(B)-tetO, but are generally able to detect variants of TetR(B) as well, such as rtTA and its derivatives, whereby TET02 is the most sensitive and promising choice. However, in contrast to TetR(B), rtTA regulator proteins are required and present in cells in much smaller amounts, especially in stable cell lines. Additionally, the regulated gene and its product may downregulate these regulators further, so that it's even more obscured. Detection of rtTA and its derivatives is more difficult than that of TetR(B) and often fails at the level of Western blotting. In such cases, PCR may be used as surrogate due to its sensitivity. Nevertheless, independent references have proven the suitability of MoBiTec's anti-TetR(B) antibodies to detect rtTA. See examples below:

Markusic et al., Nucleic Acids Res., Apr 2005; 33(6): e63
Benabdellah et al., PLoS One. 2011;6(8):e23734
Anders et al., Transgenic Res., Oct 2012, 21(5):1099–1107
arXiv:1212.5109 [q-bio.MN] (2012)

Therefore, MoBiTec shall not be made responsible or liable for any claims or loss arising from the failure of the anti-TetR(B) antibodies to detect rtTA and its derivatives.
