Biological Activity for dTAG-13

dTAG-13 is a degrader targeting mutant FKBP12F36V fusion proteins. Comprises a ligand selective for F36V single-point mutated FKBP12, a linker and a cereblon-binding ligand. Application of dTAG-13 induces rapid, reversible and selective degradation of FKBP12F36V fusion proteins in vitro and in vivo. dTAG is generalizable to a range of fusion proteins; useful as an alternative to genetic methods for target validation.

Negative control (Cat. No. 6916) also available.

FKBP12F36V can be expressed as a fusion with a target protein of interest using genome engineering techniques, via transgene expression or CRISPR-mediated locus-specific knock-in. Custom knock-in cell lines for the dTAG and aTAG platforms are available from our sister brand R&D Systems. Email TPD@bio-techne.com to enquire.

Plasmid vectors for the lentiviral expression and CRISPR-mediated knock-in of FKBP12F36V are available from Addgene.

Degradation of Myc fusion protein.
By Bikesh Nirala on 06/21/2022
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: Murine cell lines

I tested this product to degrade FFKBP12-Myc protein. It is working nicely.

dTAG-13 treatment of FKBP tagged over expressed protein in glioma cell lines.
By Anonymous on 07/02/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Glioma

Assayed the degradation of FKBP-tagged-protein with HA tag in glioma cells using dTAG-13 at 500nM concentration for 0h, 4h, 6h and 24h time intervals. Untransfected cells has no HA signal and in transfected cells with dTAG-13 treatment lead to complete degradation of FKBP-tagged-protein in whole cell lysates

Knockdown of FKBP-tagged Chromatin Protein.
By Sam Weeks on 01/30/2020
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: mESC

Assayed different dTag concentrations (50nm, 250nm, 500nm) for the knockdown of a FKBP-tagged chromatin-bound protein (180kDa). Whole cell lysate (RIPA) revealed no change to WT cells (150kDa) and considerable knockdown in all conditions after just an hour of treatment.

Works better than expected.
By Abderhman Abuhashem on 10/14/2019
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: E14 (mouse Embryonic Stem cells)

Used dTAG-13 to degrade a transgene tagged with FKBM12-F36V and HA tags to visualize the protein.

This is a western blot probed for HA tag to track degradation. All samples are treated with 500nM dTAG-13. Lanes are: 1) parental cell line, 2) control (no treatment), 3) 30 mins of treatment, 4) 1hr of treatment, 5) 2hrs of treatment, 6) 4hrs of treatment, 7) 6hrs of treatment. The constructs, as shown by the western, was degraded almost entirely (>98% quantified), within 30 mins. I have tested batch 2 of this product at conc. as low as 50nM and still just as effective. No apparent toxicity to cells. Extremely satisfied.

Targeted Protein Degradation Poster

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed. Presented at EFMC 2018, Ljubljana, Slovenia

Validating Targets for TPD Using dTAG Poster

Validating Targets for TPD Using dTAG Poster

The dTAG platform offers a generalizable strategy to degrade, in principle, any intracellular protein of interest (POI) and is a useful strategy for exploration and validation of targets. This poster presents a workflow solution for target validation, from custom TAG knock-in cell-lines for your POI, different dTAG Degraders to knockdown you POI, to automated assays for protein degradation using Simple WesternTM instruments. Data are also presented on the use of an antibody that recognizes the TAG domain (FKBP12F36V) for detection of degradation. Presented at TPD Europe, March 2022, London, UK.
