More Details
- FARNESYLTRANSFERASE (FTase, EC 2.5.1.58) catalyzes the transfer of a farnesyl group from farnesyl pyrophosphate to the cysteine residue of the C-terminus of target proteins. When not properly regulated, farnesylated proteins, including the Ras superfamily of small GTPases, can lead to developmental disorders and cancer. Simple, direct and high-throughput inhibitor screening assays find wide applications for oncology research. BioAssay Systems’ EIFT-400 assay kit provides a convenient fluorimetric method to screen for potential FTase inhibitors. In this assay, FTase reacts with farnesyl pyrophosphate and a dansyl-peptide substrate with measurable fluorescence at λem/ex = 340/550 nm. Inhibition is determined by the decrease in fluorescence.
How can I set up the positive control for this assay?
We prepared a serial dilution of the 10mM Lonafarnib stock starting at 50 µM. Please see the protocol for an example graph of Lonafarnib inhibition.
We are not observing full inhibition in our compounds after the 10 minute incubation time. Is it ok to incubate for a longer period of time?
Yes, the initial incubation can be prolonged if needed.
Does your kit include FTase enzyme?
Our kit does not include enzyme. If the customer needs to provide their enzyme of choice for this assay. Recombinant rat FTase enzyme may be purchased from e.g. Jena Bioscience, Cat #PR-102.
