ZnAF-2 DA

Fluorescent probe for Zn²⁺. Cell permeable.

Cell permeable derivative of ZnAF-2 (Prod. No. ALX-620-072). Fluorescent reagent (Ex(max): 492 nm; Em(max): 514 nm) for the detection of low concentration of zinc ion due to its strong affinity to zinc ion (dissociation constant: 2,7 nM). The sample zinc ion can be specifically detected. Low background fluorescense supersensitizes the visualization for in vivo sample zinc ion.
