SI270: Ubiquitin-epsilon-Lys-TAMRA-Gly-OH


In stock

SKU: SI-2700-0050 Category:


Fluorescence polarization substrate for deubiquitylating enzymes. The substrate consists of a 5-carboxytetramethylrhodamine (TAMRA)-labeled Lys-Gly dipeptide where the Ɛ-amino group of Lys is linked to the C-terminus of ubiquitin. The substrate allows continuous fluorescence polarization measurement of cleavage of the isopeptide bond between ubiquitin and the Ɛ-amino group of Lys. The rhodamine fluorophore minimizes interference from compounds and assay components that fluoresce at lower wavelengths.
