More Details

FARNESYLTRANSFERASE (FTase, EC 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 activity assays find wide applications for cancer research, while BioAssay Systems’ EFTS-400 assay kit provides a convenient fluorimetric method for assaying FTase activity. In this assay, FTase reacts with farnesyl pyrophosphate and the dansyl-peptide substrate releasing a product that is measurable by fluorescence (λem/ex = 340/550 nm).

Does your EFTS-100 kit include a standard or calibrator?

We do not include a standard or calibrator. 4.3 is however provided as a conversion factor for determining maximum sample fluorescence. From there, activity can be calculated.

I only have a spectrophotometer that reads OD. Would it be possible to run this assay colorimetrically?

One of the main substrates in this assay is a dansyl peptide fluorophore so the assay must be run fluorometrically

Does the kit include FTase enzyme?

This kit does not include enzyme. The purpose of this assay is to determine the FTase activity of the sample. If a pure enzyme is desired, the customer can purchase it from e.g Jena Biosciences, cat# PR-102.
