The stable Tamoxifen-like photoactivable inducer to perform a spatial and temporal control of your favorite proteins under illumination

Odoo • Image et Texte

What is it intended for? Use it to convert your inducible ERT model into a photo-inducible one. Or if you want to control transcription (using Gal4-UAS) or induce recombination (using Cre-lox) in space and/or time for in-vivo cell tracking experiments and more.

Wide applicative scope

Technology capitalizing on the versatile use of Tamoxifen-OH for controlling functions of multiple types of proteins.

Simple conditioning

Caged Cyclofen-OH is cell-permeant and can be added either in the external medium or directly injected for conditioning.

Excellent chemical stability

Caged Cyclofen-OH does not generate any basal activation of protein function and it benefits from an excellent temporal resolution upon uncaging.

Favorable wavelength ranges for uncaging

Uncaging requires either UV-A light or a strong IR laser. Visible light is inactive, which facilitates the experiments with biological samples.

Photochemical stability

Caged Cyclofen-OH liberates Cyclofen-OH, which is photostable in contrast to Tamoxifen-OH encountering photodegradation under illumination.
