Biological Activity for TokeOni
TokeOni is a near-infrared red (NIR)-emission luciferin analog. Peak luminescence at 677 nM. ~40-fold brighter than the luciferin-luciferase system in vitro, and 100-1000 times brighter in vivo. Allows non-invasive visualization of single cells deep inside freely moving animals. Ideal for deep tissue applications. Water soluble (<40 mM), orally bioavailable and brain penetrant.
This product is supplied as a hydrochloride salt, the stoichiometry of which is batch dependant. Please refer to the Certificate of Analysis to obtain the batch specific Net Product Content.
