FKBP12 PROTAC dTAG-13 (dTAG-13), a PROTAC-based heterobifunctional degrader, is a selective degrader of FKBP12^F36V with expression of FKBP12F36V in-frame with a protein of interest. FKBP12 PROTAC dTAG-13 effectively engages FKBP12^F36V and CRBN, thereby selectively degrading FKBP12^F36V.

FKBP12

FKBP12(F36V)

In Vitro

TAG-13 (1-1000 nM; 4 hours; 293FT^WT cells) treatment potently reduces FKBP12^F36V-Nluc levels in 293FT^WT cell, indicating the requirement of CRBN for the observed effects^[1].
Treatment of MV4;11 cells expressing BRD4(short)-FKBP12^F36V with dTAG-13 leads to robust degradation of BRD4. dTAG-13 treatment leads to rapid degradation of BRD4 within one hou. dTAG-13 treatment leads to rapid and potent degradation of the BRD4 fusion chimera in the heterozygous and homozygous knock-in clones, with no effect on endogenous FKBP12^WT^[1].

Western Blot Analysis^[1]

Cell Line:	293FT^WT cells
Concentration:	1 nM, 10 nM, 100 nM, 1000 nM
Incubation Time:	4 hours
Result:	Potently reduced FKBP12^F36V-Nluc levels in 293FT^WT cell.

In Vivo

Following bone marrow engraftment of MV4;11 cells expressing luc-FKBP12F36V in mice, the bioluminescent signal after vehicle or dTAG-13 administration is monitored. A significant, rapid, and durable effect on bioluminescent signal is observed four hours after dTAG-13 administration, indicating effective degradation of luc-FKBP12F36V. Twenty-eight hours following the final treatment, the recovery of cellular bioluminescence to levels comparable between vehicle and dTAG-13 treatment groups is observed^[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (2.38 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working solution concentration: mg/mL

Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL).

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
