ZnPc-O3-JQ1 is a light-triggered BRD4 degrader. Under illumination, ZnPc-O3-JQ1 generates reactive oxygen species (ROS) that degrades BRD4. The degradation of BRD4 results in downregulation of HIF-1α, thereby counteracting the photodynamic therapy (PDT) resistance induced by tumor hypoxia. ZnPc-O3-JQ1 exhibits both Type I and Type II PDT mechanisms.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
