TBI

TBI is a fluorescence enhancer with a K_d of 71 nM for the Broccoli fluorogenic RNA aptamer. TBI binds to the Broccoli fluorogenic RNA aptamer to activate its fluorescence.TBI undergoes photobleaching of its trans form, which dissociates rapidly, while cis-TBI from the media replaces the dissociated fluorophore to enable fluorophore recycling.TBI enables enhanced fluorescence of Broccoli during continuous cellular imaging (Ex/Em = 485/527 nm).

Biological Activity

Description

In Vitro

TBI (0.5 μM) binds purified Broccoli RNA to produce a complex with a red-shifted excitation spectrum, high quantum yield, and more than 13,000-fold fluorescence enhancement relative to free TBI^[1].
TBI binds purified Broccoli RNA with high affinity, having a K_d of 71 nM, comparable to BI and significantly higher than DFNS^[1].
TBI (10 μM; 1 h) exhibits low background fluorescence in HEK293T cells and induces high fluorescence specifically in cells expressing the Broccoli RNA aptamer^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
