Temporal Control (Induction Windows, Dosing)

The activation or deactivation of a genetic modification at a specific time or during a defined developmental window. This strategy allows researchers to study gene function dynamically and distinguish developmental effects from later ones.

Overview

Temporal control enables the activation or deactivation of a genetic modification at a specific time or during a defined developmental or experimental window. This strategy allows researchers to study gene function dynamically and distinguish developmental effects from those occurring later.

Frequently Asked Questions

What induction systems provide temporal control?

Cre-ER (tamoxifen-inducible), Tet-On/Tet-Off (doxycycline), and chemical or heat-shock inducible promoters.

Related Terms

Inducible Cre (Cre-ERT2 / Tamoxifen)

A system that fuses Cre recombinase to a modified estrogen-receptor ligand-binding domain (ERT2), confining it to the cytoplasm until activation by tamoxifen, thus providing temporal control of recombination.

Tet-On / Tet-Off (Tetracycline Systems)

Tetracycline-responsive transcription systems that regulate gene expression reversibly through doxycycline administration, allowing dose- and time-dependent control of transgene activity.

Inducible Allele (Cre-ER Systems)

A genetically engineered version of a gene that can be activated or deleted at a specific time by an external stimulus. The most widely used approach is the Cre-ER system, allowing researchers to precisely control the timing of gene modification in vivo.
