Ras GTPase Chemi ELISA Kit

The Ras GTPase Chemi ELISA Kit was designed specifically for the study of Ras activation, and can be used to detect and quantify activated Ras GTPase in cell or tissue extracts. Monitoring levels of activated Ras can be useful for studying novel Ras activating signaling pathways, detecting oncogenic Ras proteins, or monitoring the effects of possible therapeutic compounds.

The Ras GTPase Chemi ELISA Kit uses the unique binding properties of the Ras-binding domain of the c-Raf kinase protein (Raf-RBD) which only binds activated Ras. A GST-fused Raf-RBD protein is bound to a 96-well glutathione-coated assay plate and addition of sample to the plate results in the binding of activated Ras to the Raf-RBD. A primary antibody specific for Ras is then added to the individual wells, followed by an HRP-conjugated secondary antibody and developing reagent. The plate is then read on a luminometer, which provides a sensitive chemiluminescent readout of activated Ras. The 96-well plate is suitable for both manually assaying small numbers of samples and for use in automated high-throughput screening assays.
