EZClick™ Palmitoylated Protein Assay Kit (FACS/Microscopy), Red Fluorescence
The Californer/10028066

MILPITAS, Calif. - April 17, 2019 - Californer -- Palmitoylation occurs when fatty acids, such as Palmitic Acid are covalently attached to the side chains of cysteine (and less frequently to serine, threonine side chains) in proteins. This type of post-translational modification greatly affects cellular trafficking, compartmentalization, and membrane tethering. Palmityltransferase (PAT), the enzyme responsible for this modification, transfers a palmitate moiety from palmitoyl-CoA to the thiol group of cysteine in the target protein. Compared to myristoylation, palmitoylation is reversible and the reverse reaction is catalyzed by thioesterases. The Palmitoylation/Depalmitoylation cycle plays an important role when modified protein shuttles between cellular compartments. PAT mutations are associated with many neurological diseases and cancer progression.
BioVision offers EZClick^TM Palmitoylated Protein Assay Kit, a highly specific, simple and robust method for labeling and detection of palmitoylated proteins. The kit uses a modified Palmitic Acid that is fed directly into the cells and gets incorporated into proteins during or post translation. This post translational modification can be followed by click reaction with an azide-containing dye. The assay kit offers a powerful method for imaging localization, trafficking, and dynamics of Palmitoylated proteins, or detection by FACS for quantitative studies. Labeled Palmitoylated Proteins can be directly detected in 1D or 2D gels using the appropriate excitation sources, or enriched by mmunoprecipitation with biotin-azide or antibodies prior to proteomic analysis. We provide sufficient materials for 100 assays in a 96-well plate format.

Figure: Analysis of metabolic labeling of Palmitic Acid on proliferating cells. HeLa (105cells/ ml) and Jurkat (1X106cells/ml) cells respectively were incubated overnight with fresh aliquots of media containing EZClick^TM Palmitic Acid Label. Cells were then processed and analyzed by Microscopy and FACS according to the kit K416-100 protocol.
